IFf you mean pitiful as 'hopelessly bad at the game' I'd have to go with Devil May Cry and its entire genre.
I bought DMC4 and I just can't seem to get into it, there doesn't seem to be much in the way of a useful tutorial either. I sense it'd be the kinda game I'd really enjoy if I could get over the hump, as I really enjoyed a lot of 2d fighting games, had no trouble learning the playstyles of Killer Instinct and the like, where you had to learn how to make a combo flow.
Also guitar Hero, I've never really made it past medium difficulty, because it seemed at hard difficulty it stopped being fun and started being annoying, I played GH to feel good, not to be frustrated.
