Intelligent Qube
Roll Away
Warhammer 40k: Dawn of War (Pretty sure they're making this, but I must insist)
Fallout
Chrono Cross
Starcraft (Although honestly Dawn of War does a pretty darn good job filling the hole of sci-fi RTS)
Shenmue (I don't care how much it costs, or who pays. To not make it is a crime against art.)
Diablo (World of Diablo would be teh win)
