My brother got Mario Party 6 for me on Christmas and I think it's the best one so far. I haven't
beaten the game yet, but I have put about 10 hours of gameplay into it. I can't tell you if much is different from part 5, because I've never played it, but I can tell you a little about this.
It's pretty much the same as all the others. Mini games, roll dice, collect stars, ect.. But they added some new games that you can use the mic with (comes with the game). The gameplay sucks in the single player department, as usual. But multiplayer is what the game is all about and it doesn't dissapoint in that department.
