I began gaming, in my opinion during the golden age. Star Craft was the prime RTS, Counter Strike, Quake, UT were the main FPS's to play online it was a great time to be a PC gamer. Sure you can argue with me what was the prime of PC gaming but thats not the point. My point is PC gaming and continuations. Back in the day when a game was highly rated or had plans for some sort of side quest, expansions were made and they were made to last as long as or close to the original game and this was based on the popularity of the game. Half Life 1 made couple of expansions that followed the characteres of its own story line: blue shift (Black Mesa security Guard) and Opposing Forces (Marine security) these two expansions gave us several hours of entertainment as oppsoe to todays DLC's they offer little to the story or just slap on a couple of hours of extra stuff that may entertain us.
As the era of DLC's continue to shift, other ideas have come to mind like season pass announcements that keep us holding on to our installed game for months until no more content is distributed. Sure hard disk space has improved over time but I also have to make room for other games to be installed. I can't be sitting on a game i finshed months ago just so I can download a DLC. Just make a stand alone expansion or make it episodic similar to HL, Crysis warhead or GTA: episodes of liberty city. These stand alones turned out ot be very successful just because we did not require the actual title.
I'm the type of gamer that will uninstall the single player game once its finished. If an annoucnement of a DLC is made months after the initial realese of its title, i don't even bother to install it no matter how deeply enaged I was. Either announce a season pass or create a stand alone expansion.
