I played the previous Mario Party, and this one, I expected something really new. For the novelty side, there is the role of Bowser's interesting, with lots of twists. But otherwise, it's a little refreshed. The mini games are not so new as that, but still more or less fun.
The real novelty in fact it is the integration of Amiboo. This allows you to discover a new way of games that can change at any time thanks to the 4 shelf units changeable during the game!
