I'd recommend:
Star Fox 64, simply because it is still considered the best Star Fox game in ages, and one of the best looking Nintendo 64 games as well. The challenge isn't very high, but you'll definitely have fun listening to Peppy saying his clichéd line...! =P
Soldier Blade, this game's soundtrack is one of the best ever for a SHMUP. The power-up system with bombs and everything makes the game less challenging then it looks. You should definitely try it out if you want a new challenge, that is if you've never played a SHMUP before.
Super C, I'll simply never get bored from this game. The thing I like about it is the fact that you can get better every time you play the game, and when you're good enough to complete it without losing a credit or a life, the action seems to be at it's best! A must buy in my book.
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
