Game suggestions?

I'm just looking for some more games to play. I've been looking for some older games like Morrowind and Metroid Prime. I'm basically just looking for older games to play on pc.

I always like Roller Coaster Tycoon 2. Not really super old, but it's getting there. 

Well, the standard suggestions would be;  Half Life, Half Life 2, Quake, Far Cry, Doom 3 (or 2 or 1), Star Craft, Thief, Command and Conquer, War Craft 3 (or 2 or 1), Stalker is getting up there, Age of Empires 3 (or 2 or 1), Empire Earth, Rogue Squadron 3d...  etc. etc.
