If you had to play one game for 100 hours, what would it be?

I'm close to 100 hours on tf2.

Much like a lot of other people, Oblivion.

FF7 remake on 360 (Damnnn do I wish).

FF13 and Star Craft 2 could make me do it. If we're talking games I've already played then probably Civ 4.

final fantasy tactics.

If you mean from start to end, I'd go for GTA IV. But if you mean just a total of 100 hours with breaks in between, and just no touching other games..... Still GTA IV :P

Only one?  I can't decide, but one of these would pretty much "make" me play them over 100 hours, easy:

1. Disgaea 3
2. StarCraft II
   
3. Diablo III
   
4. Warhammer Online: Age of Reckoning

Crackdown. I freaking love that game more than anything.

Probably Oblivion or Fallout 3. Any huge sandbox RPG might do the deal.

tetris

imagine how many lines you's get in 100 hours!

gears 2 mp.

Halo or Guild Wars

Grand Theft Auto IV. Oh wait, did it already :P

I've played WoW for 100 hours and I'm pretty close on Oblivion, so either of those.

Star Ocean: Till the End of Time because that's about how long it took me anyway.

Halo 3 multiplayer

1 game, 100 hours? If I could get my hands on it Colony Wars, just so I could finaly get the Best Ending. That last fight against the Emperor's Super Titan was so hard, and I refuse to watch the best ending on Youtube cause thats cheating.

GTA 4 all the way!!

WoW or Burnout Paradise.

Well I've done it multiple times, so I guess I could do it again:  Planescape: Torment, or any of the Baldur's Gate games. 

Gears of War

Out of games I have, probably Pokemon D/P. If it could be any game, I really don't know.
