The game is played much in the vein of past Mario sports games, with features such as powerful special moves and over-the-top, arcade-like gameplay,[3] including the use of a "coin redemption system" that allows players to collect coins that are immediately spent on adding extra points to the next goal they score. Both cooperative and competitive local multiplayer modes are featured: depending on the sport, two players (two-on-two) or three players (three-on-three) can play cooperative multiplayer and four players (two-on-two) can play competitive multiplayer in two teams of two. Online multiplayer is also featured, with two players per Wii console joining up to play two-on-two matches either against friends or against random players.[4]
The game features most of the characters and locations from the Mario franchise with a few guest appearances by characters from Square Enix's Final Fantasy and Dragon Quest series of games. The Ninja, White Mage, Black Mage, Cactuar and Moogle characters all appear from the Final Fantasy series, while the Slime monster from the Dragon Quest series also appears.[5][6] Players can also opt to play as one of their Mii characters.
