Subject pretty much covers it all. My comp. can't run anything post 2k2 really, so I need more titles to hunt down.
Whoa, that's gonna be a whole lotta titles man. Which genre are you leaning toward? That might help narrow it down.
Half Life 1 and 2 and mods (IE Counterstrike, Day of Defeat, Brainbread, etc) Starcraft and Warcraft 3 Call of Duty: United Offensive Just some ideas.
basically what moomoo said Half-lifes,counter strikes,Farcry(2005 But runs on most pcs),quake 1 2 3(or open arena which is free http://www.fileplanet.com/171128/170000/fileinfo/OpenArena-0.6.0-[Free-Game]) ,age of mythology,age of empires 1 2, warcraft 1 2,Need For speed 2,Medal of Honor,call of duty,the sims. and if u really want to get to the old stuff got to http://www.emuparadise.org/ and get some nintendo games
I guess listing games I like would help to suggest others: my favourite itles I currently own are: Age of Empires III, Baldurs Gate, Diablo I & II, Deux Ex, Dungeon Keeper, Dungeon Seige II, Warcraft TFT, GTA III, Freedom Fighters, Half-Life, Heroes III, Hitman II, Manhunt, Max Payne I & II, No One Lives Forever, Planescape Torment, Quake I & II, Tribes Vengeance, Undying, Unreal Tournament, Wolfenstein. ps, I darn well sure wish Farcry would run perfectly, it runs smooth as hell, but some of the textures are shitty. My comp is great considering its 5 years old, but the video card is past its prime, and it's impossible to replace it.
