The worst Xbox 360 game I've ever played is Fusion Frenzy 2. The announcer guy is so annoying, I just played it for the 1000 points.
I remember some pretty crappy NES games from back in the day - the worst of which was Jaleco's City Connection - that game was such a dissappointment.
I would also say some of the DreamCast games were pretty sorry - like GTA- 2. I played this a couple of months ago as I had recently gotten the DreamCast again just for old times sake. I have of course played the recent versions of GTA and comparitively, this game sucked. So did Bass Fishing and Coaster Works. I had to get rid of DreamCast again (I got it while I'm waiting for Wii to be available).
