Yes I would absolutely buy it! Oh and I do not like Chaos Bleeds better than the first Buffy game at all. I've completed it so it's not like it might get better later on. Cool Bosses though, very unexpected, I won't ruin it for you!
There were things I liked better about Chaos Bleeds, like the unlockable features, all the EXTRAS! OMG it's a DVD in itself! But as far as gameplay goes, the first is far superior. I also really hated the camera angles! The first one was a better fighting game. And don't even get me started on the graphics and WILLOW's voice! UGH!
