Mario Party 9 is an upcoming party video game for the Nintendo Wii. It was officially announced at E3 2011 and will be released on March 2, 2012 in Europe, on March 11, 2012 in North America, and on April 26, 2012 in Japan. This will be the first Mario Party game in the series to be developed by Nd Cube Co., Ltd. instead of Hudson Soft.
Like previous Mario Party titles, four players take part in each game, composed of a virtual board, and move around a variety of themed lands to collect stars, while avoiding certain spaces. A gameplay element in one of the boards is that all four players will move around in one vehicle. Minigames will reappear, and have a larger focus on the gameplay than they did in the previous game.
