Just about any RPG can be pretty cool if you've got a good set of players/gm's to enhance it. Some others I love come to mind:
Star Frontiers (Alpha Dawn, Knight Hawks, & Zebulon's (Revised rules))
Gamma World (Gotta love the mutations both good and bad....)

Dark Conspiracy
I could go on with others too....but I think you folks get the picture. It's we who play the games that really make 'em great (or not).
