An improvement on the first game - with some minor disappointments.
The one thing that I do miss that was in the first game was the two different types of orb attacks. There are two different types of orb attacks in N3II, yet they don't match the intensity of the first game. One type of attack creates a new set of weapons and you can use them for only so many hits, and then it explodes killing surrounding enemies. If you hold RB, and swivel the left thumb stick, it creates a special orb attack explosion that is pretty powerful. These orb attacks are very similar with every character - it would have been nice if they were more unique. In the first game, you could save up Soul Points (from killing enemies) and do an orb attack with that - anyone you killed with that first attack would fill a secondary meter of different color soul points, which if you filled that up would be a massive unique orb attack which was always really fun to use. That would have been nice if the developers kept that.
Even though there are some things missing, the developers made improvements with the combat abilities, skill sets, magical abilities, upgrading equipment, and leveling up. So in that respect, they excelled. Overall it is a quality game, and I don't think it deserves a 3.5 at all. It's a great hack-n-slash that is a lot of fun to play online and off.
