My vote goes to two Jap titles:
Braveknight
Ugh. Gay gay gay gay. No, actually this game is an offense to gay people, too. Simply the worst I've seen yet. :::shudder::: This is why reading the NFO file is important, people!!! 'nuff said.
Jockey Road
Geez. Nice that you can speed up the cut-scenes with the "X" button, and it's even slightly funny to see characters talking like chipmunks, but COME ON!!! Did we need to see an hour's worth of cut scenes before one race??? Worse of all, that was an hour's worth SPEEDED UP!!!
How about your most hated titles?
