This is going to sound really weird, but...

...I was wondering if the kind folks on the Phantasian Productions forums would be willing to recommend any bad video games. My buddies and I want to get together to plow through a horrible title in one sitting (a la "Let's Play Sonic 2006"). I've got a 360 and Wii, as well as a PlayStation 2, but I'm not too keen on playing my PS2 for such a long sitting, especially since it's from launch.

Thanks in advance.

Bloody Roar 4 for the PS2. It's a fighting game in which the fighters transform into anthropomorphic animals. Bloody Roar 4 is unbalanced(such as a busted life system and some characters *cough* Nagi *cough* being too fast and strong), has a badly translated story and bad voice acting("What did you do to Nagi!?"). Did I mention you get an instant game over if you die agaisnt the really cheap final boss?

I also recommend Teenage Mutant Ninja Turtles 3: Mutant Nightmare. It's so mediocre and boring, IMO.

Oneechanbara for both Wii and 360. Please tell me if you end up finishing one or both, I want to know someone if someone is capable of finishing even just one of them.

I second that one.  That was my third rental when I started my Gamefly subscription back in 2006.  It was pretty lame.  I can't believe my friends and I somehow were able to sit around my original Xbox and finished the entire game (in one weekend, nonetheless).  Oh, and the AI was horrible (it was a good thing I had two others for that game, I probably wouldn't be able to tolerate playing it alone).

Oh yeah, and I dare you to play Enter the Matrix!  Not only was it boring but you may end up encountering random bugs!  I certainly remember the game freezing on me at random moments (I was playing the PS2 version, though the other versions weren't really bug free either).  It was so boring I never bothered to keep my save for that game (which is something I try to do with most of my games).

That's the only one I can think of.  Don't really have much on bad games I actually played within your limitations.
