Homeworld
Age of Wonders (If you like strategy GET THIS GAME, should be in the bargin bin)
UT
Giants
Mechwarrior 4
Motocross Madness 2
Dungeon Keeper 2 (get it now, should be in the bargin bin and as patched and stable as possible by now, a friend of mine is TOTALLY jaded on RTS games and LOVED this one GET IT)
Majesty:The fantasy kingdom (a blend of RTS and a Sim, very cool)
Drakan (best game in it's genre yet)
Freespace 2
Grim Fandango (Best game I have EVER played after nearly 15 years of gaming)
Moderatly Fun:
