Body Harvest (CRIMINALLY UNDERRATED GAME)
Seconded. Classic. Heh ha. Thanks for reminding me! Great arenas on that game. That and Mace: The Dark Age, I loved those two fighters. Nobody else did so I didn't get to whup many people, but still... heh ha, class. I seem to remember on Mace when you pulled off a certain combo it said "Ironic!" despite there being no irony at all. They must have just run out of words to use to make you feel good when you pulled off a big combo. "Brilliant!" "Brutal!" "iiirrronic!" Meh.
I third this. I loved BIO FREAKS and Mace: The Dark Age.
I'd also recommend Mortal Kombat Mythologies: Sub Zero. If nothing else to experience how ridiculously frustrating that game is.
If I recall Quest 64 was a pretty decent game if you're into turn based RPG's.
Everything else I would recommend has been mentioned :spotted owl:
