I'll give a list of one game per each system.
Nes - Captain Planet, it was insanely difficult, and it was obviously modeled after the cartoon, which was lame IMO.
Snes - Flashback, I played it for 10 minutes and it ended up back at my friends house under his bed somewhere.
Genesis - MJ's Moonwalker, Albeit MJ made some decent tunes, his games...rather, game, was pretty much crap. I hated this with a passion.
N64 - Castlevania (both of em), these were a dark stain on the history of CV games, enough said.
PSX - Parrapa the Rapper, The premise for the game wasnt bad, but I just didn't click with it.
PS2 - Unlimited Saga, I LOVE the SaGa series, it's one of my favorites, but this...ugh... if it had a better system for getting around and more detail to it besides cardboard cutouts of your characters, it wouldn't have been bad.
GB/GBC - Pokemon Trading Card Game, at the time of this game's release, I was quite a bit younger and was a bit of a Pokemon fanatic. However, this game was a joke, it made a mockery of the card game and anyone who found it to be entertaining.
GBA - DBZ: Legacy of Goku, Straight garbage... LoG2 and LoG3(aka Buu's Fury) were fantastic, but this game was...see above.
Dreamcast - Never Played it, never wanted to, never will.
XBox - Same as DC
Virtual Boy - The only game I played on this was Mario Tennis, and it wasn't that bad really.
Game Gear/Master System - Only played Sonic the Hedgehog 2, and it was ok.
That covers one game from each sys that I have actually played for a prolonged period of time. (minus the last 4, I just put them in for symmetrical reasons) I've been waiting to make a list like this for a few years actually, I just never had a reason to do it.
Did I miss the five o' clock free crack giveaway? - Tyrone Biggums.
That's right, I AM high! I'M HIGH!!!!!! - Dave Chappelle
