I finished Bayonetta 2 on Friday. Boy, what a ride. Although it was a short (8 hours for me) compared to TW101, I still loved it from start to finish. Interestingly, although it seems not so epic like the first, compared to the massive scale of the enemies, I still found it to be more epic somehow. I'd say that is because of combination of all elements: Story, graphics, characters, and so on. All in all I enjoyed Bayonetta 2 a lot more than the first and for me it's as good as TW101.
Now, after finishing the game, I dove into Tag Climax. What I first noticed it that I don't like how they handled the tag requests. You have to press start to accept it, I would have preferred a pop-up. Many people simply don't realize they have a request. I didn't know how to accept it first, too, so I started pressing buttons.
The net code seems very good. I played with a guy from France and had no lag. It was like playing local - very nice.
