Games that you didn't like at first, but then enjoyed after reinstalling it

Are there any games that you didn't like at first, thought it was terrible and would never think of playing it but then reinstall it to realise that the game is an actually fun game?

For me it was Prince of Persia because I didn't like the direction of the gameplay so I didn't want to play it at all. Then one day I felt like I'd just give it another go and now I'm constantly playing it, eager to finish it XD.

Knights of the Old Republic

Urban Assault, it was way too complex when I first tried it out (installed the demo from the Age of Empries CD) then I tried it again a couple of weeks later and I came to enjoy its complexity, gave me one hell of time. Too bad it was only a demo (fun while it lasted) unfortunately I've tried looking for a copy, no luck :(.

Team Fortress 2.

When I first got it I was a huge UT fan and struggled to grasp TF2 at all. About a year later...lol...I started to really get into it.

Far Cry 2, actually I got to 50% the 1st run, but I was bored as hell, then after a month or so I reinstalled it and finished it in hardcore

Mass effect

Lost Planet, Stalker and a couple of others I can't remember.fudgeblood

yep, those 2 also xD

Age of empires 3, it was my first RTS.

Stalker: Clear Sky

Gothic 2 and Fallout recently.

Kinda random, but the Silent Hill series...I got sick of it but I decided to continue one day, only to find that combat was fun as hell.

FEAR 1...it really bored me because it felt so different. but later that day I tried it again...and bought FEAR 2 like 2 days later haha that was one of my favorite series ever...

Half Life 1...it was boring as crap but after I played HL2 I wanted to go oldskool Valve.

World of Warcraft.

Knights of the Old Republic. When I realized it was turnbased on the tutorial level I wanted to stop right there. Probably one of my best surprises of a game.

Definitely Stalker, but I sort of lost interest again. The more i think about that game though, the more it makes me want to go back to it. I have a somewhat shakey relationship with that game

Crysis Warhead. Once the disappointment for the story passed I actually enjoyed it, even though it wasn't as good as the first.

Assassin's Creed, Mass Effect, maybe Bioshock

I have lots unfinished games 2 . but i dont this so there is one that i reinstalled and finished. there are only games that i finished and games that i played and uninstalled . latter instalted again but didnt finished again . oblivion is best example : played ~70h and got bored, next time just 30-40 h.

There have been a few for me, but the most notable ones were Dungeon Keeper, Mechwarrior 3, Half Life and Rise Of Nations

The original Earthsiege. =D

I'm adding Fallout 3 to the list. The main thing that dissappointed me was that the main quest was extremely short and you couldn't continue playing after it.

And then came the 5 DLCs, one notably Broken Steel, which is the best DLC of the 5 IMO. Now I can finally continue with my other side quests and continue exploring the world of Fallout.

Most recently would be World in Conflict. I tried playing it about a year ago, and was impressed with the graphics, but found the story really non-engaging and didn't like the camera controls, so I gave up after playing only a misssion or two.

Tried it again more recently and realized that the first few missions are a bit dull, but it gets awesome after that. I love how despite being set on an alternate timeline, everything is grounded in reality and based on actual Cold War technology and battle plans: no aliens or bizarre technology or super units like in Red Alert. I also don't mind the absence of base building. I'd say it's probably the best RTS I've played in terms of simulating what actual modern combat is like.
