I second this strongly. Also, Crash Bandicoot....BAHAHA! Nah, seriously - Overboard (or Shipwrecked for you yanks)
Starfox. The crappy game for GC doesn't count. I'm talking about another Starfox 64 game, new worlds, new story, same game-play, same barrel rolls.
I'm gonna go with Gladius on the original Xbox. I absolutely loved that game, and I am still waiting to see what happens after that cliffhanger ending. If you ever see it in a bargain bin consider picking it up. It was a turn based rpg of sorts. Some compare it to Final Fantasy Tactics. (They set it up for a sequel but due to poor sales cancelled it...which I think is retarded)
Claw for PC, Cat Pirates with treasure and brutal platforming. Hell if I'm ever gonna finish it but Panzer Tactics; takes all the cute out of TBS and shoves in dry, dull, tactics. A man's war-game where it kicks your unthinking, uncalculating ass.
Brute Force Blinx: The Time Sweeper (the shitty sequel does not count. at all.) Jet Force Gemini Jet Set Radio Future MechAssault <3 Dark Watch .... ........ ..........Ultimate Spider-man.
