 Game History
Mario Stadium would be the first court for the Mushroom Tourney and the game in Mario Hoops 3-on-3. It is a basic court with no gimmicks attached to it and is usually a good starting court for a game of pure basketball. It is a regular stadium with stands, a big screen and banners around the sides with the Square Enix and Nintendo logos on them. The audience would be filled with Shy Guys, Goombas, Piantas and Toads that will all cheer for the player. Each tutorial in the game will take place on this court.
The court would return in Mario Sports Mix, Players would be allowed to play each of the four sports on this stadium and also watch any of the tutorial movies as each will take place on this court. It can be used to be a basketball court, an ice hockey rink, a dodgeball court, and a volleyball court. The crowd will cheer for the teams in the match. In Bob-omb Dodge, this would be one of the three courts played on where the player will have to dodge the Bob-ombs.
Mario Stadium would be the holder for the grass, hard and clay tennis courts in Mario Tennis Open and one of the courts that is available from the start. It would be the starting court for this game and be the basic tennis court for the Hard Court, Clay Court and the Grass Court. Players will also play the special game, Ink Showdown on this court. These three courts will appear in the final World Open Tournament, the Champions Cup.
