I played the demo for Bayonetta and I was underwhelmed; I didn't really like the gameplay or the witchtime. To be perfectly honest, Bayonetta felt.... a little too schizophrenic to me; the camera bounded around too much for my taste. I bought Darksiders and I love it. The first hour made me regret buying it, but I was really pulled in after that and i've enjoyed it since. I recommend Darksiders, but I also own it for the 360.
