Oooh I'd like to take part in this:
1: Minigames were epic, boards were pretty good (8/10)
2: Very awesome boards, fun minigames, costumes are a nice touch (9/10)
3: The best of the bunch, Duel mode was an awesome addition, great new items, fun story mode with a boss battle, and Waluigi (10/10)
4: Interesting game, the story mode was pretty good, the boss minigames were fun, and the extras room was cool (8.5/10)
5: Honestly, I think this surpassed MP4. I loved the machine mode, loved the new orb system, and loved the paper mario references (9/10)
6: Fun. Fun. FUN! Return of the bank was very nice, the day/night system was awesome, story mode was a bit weird from what I remember (8.5/10)
7: At first I didn't really like this game, but then I adjusted to it. Char-specific orbs were a nice addition even though Yoshi and Birdo were overpowered, Windmillville will always be my favorite board (7.5/10)
8: No offense, but I really don't like this game. It moves slowly, the graphics never improved, minigames were REUSED for more than one type (such as the same minigame being played differently for Duel and 4-Player), Story mode was torture, this game is only fun when playing with friends, (6/10)
GBA: This game is actually a decent solo adventure. Collecting gaddgets is fun, collecting minigames was enjoyable, the fact that almost every minigame keeps your record is also cool, but you have to forget it's mario party because it plays nothing like it (8/10)
DS: Very good game. Minigames are fun, boards are pretty cool, puzzle mode is the bomb just for the music, single-card play was a smart move, but minigames are REUSED AGAIN (8/10)
Oh, and for Halloween, I handed out candy as Sora (I made an epic-looking keyblade out of a Shredded Wheat box and a croquet stick) to a kid trick-or-treating as Sora. The funny thing was that I was dressed up as young Sora, and he was dressed up as KH2 Sora (But I was taller than him XD)
@Dajayman: Yeah, just about everybody who played the rotate minigames did. I heard Nintendo released special gloves that you could wear to prevent getting blisters (I never got them, so my hands always hurt for a few days after playing Minigame Island -_-)
