It's a quite faithful sequel when it comes to game mechanics (though you can't ride on balls or skateboards anymore) with lots of interesting characters to choose from. The story, however takes a back seat this time and doesn't make much sense. Admittedly, the writing was never a strong part of the franchise but the whole game decides to go meta in the style of Cabin in the Woods which would be fine if it was somehow lampshaded earlier.

When it initially released some (if not most) characters were broken and their moves were not exactly working as intended or not balanced enough. As of now many of the issues seem to have been fixed and the characters are playable and most of their moves are usable for the most part.
