This is by far the worst Mario Party game. But it's not all bad. It's just not playable over-and-over again like the previous ones. Mario Party 2 is still the best in my mind; and stands out the most. I guess that's just my opinion, though.
Overall, if your a fan of Mario Party; you'll be a little disappointed by this title. But it does have it's fun features, so at least give it a chance. It might just be worth it (and because I said so =P)
