Gotta test out the FE games I havent played and pick on of them.:P

Unreal Tournament 2003 (PC)
Half Life 2 (PC)
Crysis (PC)

Reason? The mods for these games are fantastic so if I want something different I can just play another mod.

Metal Gear Solid 4
Super Mario Galaxy
Super Smash Bros Brawl

All right, well it'd probably be multiplayer stuff if you're stuck with three games forever. I'd go with Team Fortress 2, as it's the only online shooter I've gotten into. Rock Band for some kick ass local multiplayer.

And for a single player game, can't really decide. Thinking something like skate or Tony Hawk 3, see how many awesome replays I could capture. Then I'm thinking maybe the Sims or Roller Coaster Tychoon, for the more builder aspects. Or even Boom Blox. Actually screw all that, I'd take Endless Ocean. Need something to relax to after the other two, and after 20 hours there's still a bunch of creatures I haven't found in that game.
