I'll say any 3D game of any kind and leave it at that.
I will say the NES M.U.S.C.L.E game was mortifying...

but then people warned me in advance that it sucked. But hey, I got it for 3 bucks at Gamestop....
another disappointment was when I found the NES "Dragonball" game (long story, years ago I found the real Japanese verion on an Emulator)
other that the fact you get to give Roshi panties and have his nose bleed, it was fun for like 2 seconds.
