I've got so many games I need to get through. Definitely want to play Castlevania soon as what I played of it on the 360 (about 3 hours) it's really good.
But I am a sucker for generic hack and slash games.
Haven't played one for a while myself, but I had fun with the demo ages ago. It's nice to have a bit of a mindless game to pop in when you want to play something but you're not quite in the mood for an RPG.
