Dammit, I hate these limits you people are always imposing.
Well, my list would be, in no particular order,
-Freelancer (I blame Disco)
-WH 40k: Dawn of War (I <3 Tau, yay for Dark Crusade)
-Half-Life Two (Yes, I'm aware that One was better... Shaddup)
-Elder Scrolls Three: Morrowind (Sure, the game engine may be fail, but it's still fun)
-Fallout Two (Yeah, I know I'm off by two years, but that game was sheer awesome)
