How Diablo 2 Was Almost Lost, And Why A Remaster Is Less Likely

"Irrevocably, fatally corrupted."

39 Comments

As part of wide-ranging and fascinating conversation at ExileCon 2019, the creators of the Diablo franchise--Max Schaefer, Erich Schaefer, and David Brevik--shared a number of stories about the series that popularized the action role-playing genre. One of the more intriguing stories came about when the moderator asked the panel to recall a scary moment in Diablo II's development.

There was one story in particular that sounds like a developer's nightmare. Erich and Max Schaefer recalled that in the 11th hour of Diablo II's development, the entire backup of the game's source code and assets was lost. "Not just our code, but all of our assets. Irrevocably, fatally corrupted," Max Schaefer said.

His brother Erich added, "It's all gone. We were supposed to have a backup but neglected it. We spent a day or two in sheer panic."

The team at Blizzard North was thankfully able to reconstruct a lot of the code and assets from the version of Diablo II that developers took home to play. However, the root code and assets were apparently lost, which means Blizzard would have a tough time making a Diablo II Remaster today.

"[We] finally rebuilt a lot of it through what people had at their homes," Erich Schaefer said. "I had a big chunk of it. Went home, pulled out the hard drive or whatever we did back then. Spent a few days reconstructing it, which ended up working fine, except that we lost all the history. We lost a lot of the assets, art assets. It would make it very difficult for Blizzard to do a Diablo 2 remaster because all the assets we used are pretty much gone. They'd have to make them from scratch."

One of the pre-BlizzCon 2019 rumours was that Blizzard was planning to announce a Diablo II Remaster, but that did not materialise. The company did, however, announce Diablo IV to much celebration from fans following the tepid reception to the Diablo Immortal announcement a year prior.

The Schaefer brothers and Brevik developed the original Diablo at their independent studio, Condor, which Blizzard acquired just before the release of the original Diablo in 1996. Erich Schaefer said the buyout couldn't have come at a better time because Condor was in dire financial straits. He recalled that the studio was just scraping by, and apparently didn't have enough money to pay some of its taxes.

"We never paid our payroll taxes. These are taxes we withhold from the salaries of our guys, and we're supposed to mail them to the government. We never mailed it to the government," Erich Schaefer said. "We were pretty much out of money. We come in one morning and there's a notice on our day that's like 'Three days to pay or you're going to jail.' It was rough. It was really scary. We scrounged up some money [to pay the taxes], and luckily the deal that turned us into Blizzard came around right at the right time to save our butts."

Also during the panel, Max Schaefer revealed that Condor signed to make the original Diablo for $300,000, which was "woefully insufficient." He said the studio, at the time, was "always completely out of money," which was very stressful. No doubt the financial security that an acquisition by Blizzard could offer was attractive to the team, which eventually went on to make Diablo II as well.

The original Diablo exceeded all expectations. The Schaefer brothers said they envisioned the game selling 20,000 copies, which would be enough to make a sequel. The game of course sold many more copies than that, and it helped establish the ARPG genre that is immensely popular today.

The Schaefers and Brevik left Blizzard after Diablo II, and went on to create new studios and work on new projects. Brevik held a number of positions at different studios in his post-Blizzard career. Among his most notable new positions was head of Gazillion Entertainment, which made Marvel Heroes. He then started his own studio, Graybeard Games, which is currently working on an ARPG called It Lurks Below. Just this week, the game was announced for Xbox One, in addition to PC.

Max Schaefer now heads up Echtra Games, which is making the recently delayed Torchlight Frontiers, while Erich Schaefer went on to create Double Damage Games, which released Rebel Galaxy in 2018.

Brevik said he sees the ARPG genre as one that still has lots of room to grow and evolve over time. He said he can foresee elements from MMOs and ARPGs coming together to form a new kind of game that is more socially inspired, with players working together to take on raid-style bosses and other cooperative elements. He said Gazillion tried to achieve some of this with Marvel Heroes, but unfortunately that game was shut down at the end of 2017.

I suppose companies don't want to waste time recreating 1:1 copies of things for no benefit.

Granted, Blizzard will resell a remaster at a cost to consumers instead of just patching the game (hello SC:R), but if the source and assets are poofed, then that's a lot of work to do for something that can't make enough money to cover the dev time that could've been spent on other, more "lucrative" projects.

If anything, a small subset of die-hard fan developers could do it without much impact to Blizz, but will that actually happen?

Every once in a while somebody comes out and says how difficult it would be for D2 to be recreated up to modern standards.. I call it all BS.. if Blizz wants it they can make it happen. Don't see how D2 is more difficult than W3, the latter with all its races, units, buildings, voices, heroes, etc..

Assets being lost is BS. Blizz would need to redraw them in HD anew anyways, like they did for SC. And also - the advances made in reverse engineering source code have been amazing.

Development before Github. Having learned programming in high school and seeing a glimpse of how things used to be done I would have hated working in "the old days."

Wow, some serious revisionist history here. When Blizzard bought Condor, Diablo wasn't on the verge of release, it was still in an early alpha stage back when the game was turn-based and used digitized clay animated figures for the characters. It was at Blizzard's insistence that they made the game real-time and used more conventional graphics. Blizzard also put all their other work on hold and put all their resources towards helping Blizzard North finish Diablo, which is why StarCraft was delayed for so long.

In other words, Blizzard North wouldn't be who they were without Blizzard's talent and resources behind them. When the Blizzard North team was eventually fired because of their hubris, they formed Flagship Studios and made Hellgate: London which was a mediocre game with bad support and a terrible subscription model.

If they ever figure out how to monetize it as a "game as a service", they'll be able to remake it right quick. Money is Blizzard/Activision's god, and they will stop at nothing to worship at its altar. Lacking source code won't stop them.

@Royas: pretty sure he's talking about artwork and such... I was confused at first too, but they salvaged the code and sprites for the game, so what is very likely missing is concept art, behind the scenes story stuff, and so on....

He also said they would have to make stuff from nothing... there he's also obviously not talking about the code or spites, because they wouldn't use those for anything anyway, except maybe inspiration, which they can get from just booting up the game

@LordCrisp: I assume he means the 3D models and high resolution assets that the sprites were created from.

What about just adding full widescreen support for it though with integrated modern battle.net support? I'd be fine with the game playable as it is from the launcher. Trying to play the original version doesn't work well on my system, ironically it performs very badly despite having vastly better HW.

@oddsnake There's nothing ironic about this. Emulating past technology has ALWAYS required more power than the original hardware the tech ran on. For instance, N64 games, which ran on a 62.5mhz cpu and 4mb memory, ran very badly on a, back then, monstrous Pentium 2 with 96 mb memory and an 8 mb GPU. The reason behind this is that today's technology isn't built around running old tech codes so an emulator needs power and memory to act as if it was a machine from back then and it also needs power and memory to run the game. This is a highly summarized explanation, but if you want to know more, there's a lot of documentation available on Internet explaining everything about the history of emulation.

Reminds me of the story about how Pixar would've lost virtually the entire code for "Toy Story 2" if it hadn't been for one of their workers who had taken a server home with her so she could do some work while she was on maternity leave.

I wonder if "Diablo II" will eventually join its predecessor on GOG.

No vector graphics generally means no "HD remaster" whether the source is gone or not.

@basketballfan: Not really. Many "no vector graphic" games have been remastered over the years and several of them actually are more "rebuilt from scratch" games than remasters. The word "remaster" has become very loose over the time and pretty much any game that is graphically and audio improved, but which ahd their gameplay kept intact are sold has remasters by companies.

Hows this? Blizzard will NOT invest the time recreating the hundreds of thousands of visual assets this game had. That better? Wow.

@BabeNewelll: Good, after all lot of devs say something is hard or not worth it.

Then hobbyists start make remakes of Resident Evil, Megaman, Medievil, Crash Bandicoot etc., these companies in panic try to keep these projects shut down. And one day then announce "here is our remake of game X"

Not that I mind because every remake of a game I once owned is an automatic pass. It's good they make Diablo IV instead of II Remaster. I wish they also made Resident Evil 8, Crash Bandicoot 4, Medievil 3 etc. But at that point the devs start to say it's easier to remake an old game than to make a new game.

I dunno, its possible, but I dunno. Blizzard also said WoW Classic would have been extremely hard to redo, but once they saw there was money to be made by doing it, they sure hopped on it pretty quick. If they deem Diablo 2 Remastered will make them enough money, you bet your ass they will start working on it tomorrow.

I really don't get why people make this "source code" out to be such a big deal. Diablo 2 is a really old game. I'm sure it's been completely taken apart by now, every part of it. There's so many mods for that game that change every aspect of it and add HD graphics, etc. I really don't see why this should be such an issue. What is probably going to take some effort is to recreate all those old low res 2D graphics in Full HD or 4K. My guess is that that's why Blizzard won't bother. But how big of an issue was that in Starcraft?

There's even a guy who's created some algorithm that can automatically upscale the game's textures to HD. So Blizzard could just make use of this kind of technology. I really see no reason for them to not do a remaster. There's probably hardly a game that people would like more to see a remaster of then Diablo 2.

@Atzenkiller: If you upscale Diablo 2 to 4k resolution you'd be able to see the entire map in one single view point.

Yes, you can scale these old games up but it just makes the game ridiculously small to see.

The point of redrawing and remastering these games in higher resolutions is to draw textures and detail that would necessitate the higher resolution. Natively drawing the existing graphics in higher resolutions is pointless.

Considering Square had a similar problem with FF8 yet we still got a remaster after all these years, its still quite possible for D2.

@imajinn: they has to rebuild FF8 from the ground up for the remake, and there's more that goes on behind the scenes in a game like Diablo, so it probably is harder to do.

yeah no kidding eh. Probably now adays everything is automatically backed up locally and offsite.

Guess they were too cheap and lazy to buy some extra hard drives or cd-r's to do some backups each day.

Blank cds were expensive in the mid 90s (10-15 bucks each) but come the late 90s were pretty dirt cheap, and a big company like them could have afforded to spend a few dollars a day to burn a copy of their work.

No excuse really.

@Yams1980: Even the smartest person fails to back up thier work and lose their progress and they are not the only company to do this and it will not be the last and hopefully they learned from this and probably did. How ever I am happy that I was able to play D2 and even with the lost of the necessary code or properties I would be glad to play an modified remaster of D2.

@lonewolf1044: Exactly. Human error is the reason why most companies now uses auto-back-up scripts to make sure everything is archived at all time. There's nothing wrong about human error because there will always be such errors. What's wrong is doing nothing about it.

And yet they were able to continue updating it and release an expansion? I don't know if I buy it.

People want a remaster insofar as they want the game to run on modern OS's well, and maybe see console ports, those don't really require 100% original assets, just essentially modding and updating.

@Xylymphydyte: Well, you can already run it properly on Win 10, even with the original graphics since someone made a 3dfx Glider that emulates those graphics cards a long time ago. The main issue is that the game was built to run at a very low resolution. 640x480 for the main game, which was extremely low even at the time. So even if you increase the resolution now through a mod, it's like the game just zoomed out really far so everything becomes tiny.

But if Blizzard really doesn't care at all about doing a remaster, then it's time they handed it to GOG. They've already rereleased Diablo 1 and are probably already waiting for it, as are many players. Maybe GOG can make some of the necessary changes to make the game more playable that mods don't provide yet. Although from what I hear what they usually do is to just add a bunch of mods to the original game. But if the game got rereleased officially, then it might get some more attention and maybe modders will go through the effort of improving it further. Waiting for Blizzard to do something really seems pointless by now.

Like I said, if there's even software nowadays that can upscale textures for you, then there's really no excuse. And Blizzard was still releasing new patches for the game a few years ago, so they do seem to care about it.

@Atzenkiller 640X:480 wasn't extremely low at the time. It was the second highest resolution back when D2 released (800X600 being the higher one among the "SVGA generation"). Higher 4X3 resolutions came out much later and mostly happened after PC LCD display became a thing.

However, I do agree with you that Blizzard has no excuse. No matter what, it's always possible to remaster. Some remasters were even completely rebuilt from scratch, with only spreadsheets and matrix kept intact and original.

@heqteur: Dude, tell those stories to someone else. My old analog monitor, which was the very first PC monotir my father ever bought and that he kept around for many, many years, was able to display resolution of up to 1280x1024 at least. And no, we weren't rich and that thing didn't cost thousands of Dollars. To say that 800x600 was the standard at the time D2 came out is ridiculous. I've always had Windows running at 1024x768. And 640x480 was extremely low res. I remember the first Tomb Raider on pc also only ran at that resolution and it looked like you were playing on a NTSC tv as a result. Definitely not something I was ever used to since I've started using Windows with Win 95.
