How about "Obscure" for the PS2? That's a pretty Obscure game....

It was pretty decent, and even got a sequel...
ObsCure for the win!
I particularly liked Shannon, though her appearance changed between games. She sorta looked like Silent Hill 3's protagonist didn't she? I loved how you could end the game with one living character. Seriously, getting your friends killed was hilarious. I crushed Josh under the lift.
I think Vexx was a pretty low-profile title, and I REALLY enjoyed that.
Chaos Legion seemed pretty understated too. Oh, and there was this PS1 Arena Brawler game where one of the characters had sawblades for hands, it was really fun. You could detatch his sawblades and set them up as traps. If anyone can tell me the name, I'll love you.
OH! Also, did anyone ever play Demo 0.1? You play as a T-Rex in a black arena, don't nothing but walking and roaring. That was pretty obscure.
EDIT: These two probably aren't obscure, but they were very memorable:
Yu-Gi-Oh: Forbidden Memories.
Croc
Galaga (PS1) I can't remember if it was 2 or 3...
