May seem like another Mario Party 1, but it's not...
Characters: Same as MP1, no additions
Stages: 5 new stages, each with its own theme, like a pirate-themed stage and a space-themed stage.
Minigames: 43 new minigames, with a couple of reused games from the first game. Battle, Duel, and Item minigames are introduced in this game.
At first, you think that reusing the same games from the first game would make this one bad. But, to keep things entertaining, they are remade so they are not carbon copies of the same games you see in MP1. Also, these minigames are a lot less annoying than the previous game. For one thing, I haven't seen any game which requires the player to rotate the analog stick. I forgot to mention that in my MP1 review. That was without a doubt the biggest problem of the original MP. There's no such problem in this game.
There's nothing else I can really complain about this game. The formula still works, doesn't it?
