Street Fighter - any of them. I don't have the reactions to string combos together, I can barely even pull off a shoryuken. It doesn't help that all the friends I play it with grew up playing the II arcade machines every day, and unlocked all the characters from IV in about a day. Continually losing is no fun.
Fable II - could have been so, so much more than it was. The potential for a decent RPG was there, but they never followed up on it. No real incentive to do the side-quests either, except to lengthen the game a little so you didn't feel like you'd wasted *quite* so much money.
Obsidian - Boring. Badly made and boring. Then again, I played Fallout 3 first, so I was probably spoiled by that. I kept trying to enter VATS during a swordfight...
