Mario Party 4 is a 2002 party video game developed by Hudson Soft and published by Nintendo for the GameCube. The game is the fourth installment in the Mario Party series and is the first game in the series to be released for the GameCube. Like the previous games in the series, it features eight playable characters: Mario, Luigi, Princess Peach, Yoshi, Wario, Donkey Kong, Princess Daisy, and Waluigi from the Mario franchise, who can be directed as characters on 6 themed game boards. The objective is to earn as many stars as possible, which are obtained by purchase from a single predefined space on the game board. Each character's movement is determined by a roll of a die, with a roll from each player forming a single turn. Each turn is followed by a minigame in which characters compete for coins they can use to purchase items and stars.
