I wasn't aware mini-games were taken out of Mario Party 8. Where did you read that Viper?
The first three are by far my favorites (although I save my game each turn and reset whenever a rotate the control stick game appears in the first one since my controller is getting pretty beaten up by it.
Mario Party 6 was pretty good, but I still haven't gotten over how they "replaced" items with orbs. It's a shame that the Mic games haven't had as much popularity since MP7, they were pretty fun. (Mario Party DS's mic games only require blowing)
Mario Party DS was ok, but the boards are horrifically small ( a single item can typically take you around the entire board if you know how to use it), the game feels a little low budget, and the ai is the stupidest in the series. (I've had several instances where I placed a 2-star steal hex in front of a star, the ai had a choice whether to take the route with the star and hex or take the safe route, and land on the hex in that turn, it's even more hilarious when I'm up next and am only two or three spaces from the star anyway. lol)
BTW, has anyone ever gotten 999 coins via Game Guy in Mario Party 3 or the Bowser Roulette in Mario Party DS? I have. lol
