Mario Party 4 is the fourth installment in the Mario Party series and the first for the GameCube, which was released in 2001. It follows the original's style of board game-esque gameplay, as well as the use of many items and mini-games. The game's goal, as with most of the others, is to collect stars. It is also the first Mario Party game to allow players to team up. This is the first Mario Party game not released in December for Japan.
During a pleasant day in the Mushroom Kingdom, Mario and his friends are lounging around outside Princess Peach's castle when a mysterious floating present appeared. Shocked by what they saw, they moved closer to the mysterious present, when it suddenly changed shape and opened revealing Toad, Koopa Troopa, Goomba, Boo, and Shy Guy to be inside. Toad then proceeds to explain that with the help of the party cube, they would be celebrating Mario's birthday (the character whose birthday it is depends on the character selected for story mode). Toad then declares the party started and the game begins.
The character chosen must then go through all the boards of the game, each hosted by the board's creator: Toad, Koopa Troopa, Goomba, Boo, Shy Guy and later Koopa Kid (Mini Bowser in Europe and Australia). After the player has won on the chosen board, they will be presented with a gift by the hosting character, only to find out that in order to claim the present, they must beat the host character in a duel mini-game. Once all the main boards have been finished, Bowser will show up and disrupt the party, claiming that he too has a present for the player and demands that they play on his board. Once the player wins on Bowser's board, Bowser will challenge the player to his final duel. Once Bowser loses he will trudge off slowly, mumbling sadly to himself and he will drop a present behind; Mini Bowser will then appear and tell the player that Bowser had always intended on giving them the present. After the last present has been received (the last present is always Bowser-themed), Toad will announce that one more present still has to be given. A Power Star will then show up and give the player a constellation of themselves. After this, the ending credits will play and the story mode is completed.
