People make a big deal out of a bit of fps drop, but it's never even struck me as a problem. The game is smooth enough, pretty and the action is satisfying.

There is very little tutorial, but an inquisitive spirit will manage to understand all the necessary subtleties in the combat and crafting. The combat has a lot of depth once you've upgraded the weapons a few times, while not veering into the ridiculous spectacle fighter like Devil May Cry. 

I really liked the story and getting all the endings was a ton of fun.
