If you had to play a game forever...

Left 4 Dead, I just cant get enough of it.

Loopholes aside: Civilization IV, all add-ons, all mods.

 

[Ben Legend]

Gears of war 2 online. Playing on it for the rest of time would probably give me a chance of reaching level 100.

I don't know. The first thing that comes to my mind is Legend of Disgaea, but no. I don't think I can choose one. Probably an MMO, though I have no clue which one.

The original Final Fantasy, it would be fitting, cause the ending is a time paradox.
