I think the original Half Life belongs somewhere on this list...everyone remembers the first headcrab leaping out of the shadows, just hoping to eat your face. And AvP belongs somewhere on here...

Well, Guild Wars factions also runs just as well as Guild wars on older comps. Also, for you guys who can't run BF2, try downloading warrock. Yeah, it's free, but it is a pretty good game, and with decent graphics but still enough to run on older comps.Hmmmmmmm.....I can also run Command and Conquer Generals, a great game.

1. Super Smash Brothers Melee-This game is nigh endless. there is always some secret to unlock, always some glitch to discover, something.....anything. This game is pure fun, and never gets old. 2. Halo 2-Hear me out. The single player campaign, fun though it may be, is too short. however, online play with this game kicks ass. 3. Metroid Prime-an amazing game. Even I, a video-game purist, haven't uncovered all the secrets this game holds. 4. Star wars: KOTOR-Yet another great game. I never get tired of this game for the sheer fun factor. A little tedious at times, admittedly, but still an amazing achievment. 5. Guild wars-I don't need to say anything.

1. Lego Star Wars: there is nothing more satisfying than ripping Legos to bits with a Wookie. If you don't enjoy that, you can't be cool. 2. UT2K4: any game that lets you have a gun with spider mines has to be cool. I mean, I have a feeling everyone wishes they had a spidermine. they are just funny to watch as they chase down their unsuspecting prey..... 3. RE4: because it is RE4. It is not possible to deny the awesome awesomeness of this game. Plus, it has a giant man-eating fish. Cool. 4. Knights of the old Republic: because you can finally play the Dark Side. Force choke is just funny to watch. 5. Guitar Hero: do I need to say anything?
