For a while now, we've been getting yearly Mario Party updates. The game that started as a fresh take on board games during the Nintendo 64 era quickly turned into a hit. Like every company, Nintendo and Hudson like money, so the sequels kept popping out like kids from a trailer park "socialite". After a while, though, the magic died and we were left with sequels most well-informed gamers didn't care about.
What's so different about Mario Party 8? Why should anyone on Nintendo-Play care about another sequel? Well, just like most "revived" franchises on the Wii, the controls are the agent of change that we care about.
There's the ability to have your own file separated from that of your
brother's or sister's. You'll link your profile to your Mii, too, so
you can easily identify which is yours if you find it difficult to
remember if you chose file #1, file #2, or file #3.
The game's new setting is a carnival. In here, you'll quickly meet a man and his hat friend. They'll be your guide through the whole game, so you better get used to their little skits.

The main menu is just a screen with the different modes displayed. In my opinion, Hudson lost a great oportunity here. Just letting you explore the carnival with your Mii or your favorite Mario Party character would have felt so much better than the mode picking. Still, the menus are good enough, although there's some obviously questionable decisions in there.
Let's get to the meat of the game. The party tent. In this tent, you can choose to either go on Battle Royal, which is your classic Mario Party four player game; Tag Battle, which is a regular game except you pair up with someone and at the end of the game your stars and coins are summed up to see which will be the Super Star Team; and finally, there's Duel Battle, which is a two player game. Personally, I still prefer the classic Battle Royal, but with friends, Tag Battle can be pretty good, too.
The game plays as usual. Jump to hit the dice and see how many spaces you'll move. The main goal is getting stars and coins and after every turn a mini-game will put the four players against each other in a competition for coins. You can use power-ups, now called Candy to help you get to the stars faster and help steal coins or stars from your rivals. It's still the same game from Nintendo 64, but if you liked it then, you'll still love it now.

The boards have stopped using a top-down view. Now, each board has a different view point which may be confusing for veteran Mario Party players but you'll get used to this soon enough.
The mini-games are where the game suffers. Some games work well, but for the most part, the developer insisted on using the Remote controller style, which doesn't quite work. In fact, some mini-games will be very hard to control because you're expected to twist your wrist to the right 180 degrees (the awkwardness will be twisting to the left for those of you who are lefties). It's like the game expects you to break your wrist for it. In these mini-games, I've found that using Wario Ware's "sketch artist" position works best, so if you see one of these awkward mini-games, quickly change positions and hold the Wii Remote like a pencil.
