I agree. Although I love luck based minigames, the entire game shouldn't be based so much on luck. I did love the boss battles, and I would like to see them in future Mario Parties. The Captain Events were fun too, and could still work even if they return to the classic Mario Party, as having players move around on their own. I also really liked playing minigames only when landing on a minigame space, and being able to choose the minigame.
I really miss the coins, and using them to buy things though. I would also like to see some remakes of boards from old MP's, along with amazing new boards of course.
