Mario Party 9 is out today on the Nintendo Wii in the US

"Mario Party 9" for the Nintendo Wii is released in North America today, having already been released in Europe and Australasia last week.

It is the second Mario Party game for the Wii, the ninth on all Nintendo home consoles, and (slightly confusingly given the name of the new game) the twelfth overall.

As with all the previous games in the series, the new one features a variety of classic Mario franchise characters which two to four people can play as, competing in a virtual board game interspersed with minigames. There are 80 minigames in Mario Party 9, which have a larger focus on gameplay than they did in the previous game, divided into four categories: Free-for-all, 1-vs.-Rivals, Bowser Jr., and Boss.

Sounds like a lot of fun to me!
