Super Paper Mario, I never got into the game, I left the game in Ch. 2
I'm not saying it's a bad game, I just never got interested in it

another was Mario Party 5 where I thought it would be as great as 4, but it wasn't. I was really disappointed when items got replaced by stickers...

Offtopic.

Hey Thanny, is your name Danny, but you pronounce it Thanny?

Warioware Smooth Moves. Gosh that game is crap.

I don't usually buy bad games, but so soon after the Wii's launch, there weren't many games available, and it looked like a promising party title pre release.

House of the Dead 2 +3 , it just has aged poorly and dropping pennys to play for 10minutes fun, is ok at the arcade, but the game is crap on a console. I only got it because RE UC was so great and I wanted more light gun goodness. Sega should have given the wii a HoD game made from the ground up, but they choose to a ubisoft and I got ripped off.

splinter cell chaos theory, i found it really interesting but qhen i got to play it i didn`t enjoyed it at all, also call of duty 3, i though i`d really like the world war scenario...but that got so boring after the second mission.

PS2. The only game that was worth playing for it was GT3. After finishing that I bought a xbox and never regretted it.

Wario World for the GC. Pure crap.
Also my PS1, I regret it because I had to borrow a N64 from a friend to play the best games.

Unreal Tournament III for PS3 - no coop or splitscreen was very very disappointing

@imthelegend

ps2 a regretfull purchase? thats the first time i think ive ever heard that

Unreal Tournament 2004. I just bought it recently. The amount of servers actually playing is much smaller than I thought it would be, and the game itself is just a mindless frag/spam fest. I would be even more disappointed if I paid more than $15 for it.

Also, my PS3.  While it does an awesome job playing/upscaling PS2 games, it so is not worth the $600 I originally paid for it.
