Favorite "Bad" Game

Basically games that were generally not well received or scored mostly negative reviews that you enjoyed. Anything that averages under a 70 on metacritic qualifies. I'll start:

Marvel Nemesis: Rise of the Imperfects, just a fun mindless brawler.

Crimson Dragon, excellent art style easy to pick up and play and dragons look pretty cool.

Geist, probably one of my all time faves really, very original and cool gameplay mechanics.

Custom Robo, really liked the customization and combat.
