Could this game be competition for Mario Party? Answer: Definitely.
For anyone who thinks Wii Party is a Mario Party rip-off, you couldn't be more wrong, this game almost has no resemblance to it.
This review is going to be a bit bias, because I do not like Mario Party all too much. Why don't I like Mario Party? You see, Mario Party revolves too much on luck, and plus the AI is cheap, not to mention the fact that the whole game revolves around board games and minigames.
The reason I adore Wii Party, it because it has more than board games. Wii Party has two entirely different board games, and many other unique and very fun games.
Some of the more fun games in Wii Party include: Spot the Sneak. Spot the Sneak is a very creative game where one person gets an advantage in a minigame, making most of the minigames easier for them. The "sneak" is chosen at the beginning, right before the first minigame. The sneak must try to keep his/her identify of the sneak a secret, because after each minigame, everyone chooses who they think the sneak is, and if they get it right, they steal points from the sneak.
My favorite game in Wii Party is "Hide and Hunt", a game where you hide all four Wii Remotes, and everyone else has to find them. It's simple, but very fun.
There are so many fun games on Wii Party, I cannot name them all, but one thing I can tell you, is that Wii Party is probably the most fun on the Wii I have ever had, and I have a lot of fun Wii games.
If you are looking for a great party game, chose this one, it's fantastic!
