Mario Kart: Double Dash!! is a racing game developed and published by Nintendo for the GameCube and the fourth installment of the Mario Kart series. The game was released in November 2003 worldwide, being released in Japan first. The game, while retaining many aspects of previous Mario Kart games, such as selecting a Mario franchise character as the player's driver and the familiar item-based weaponry that the series employs, introduces a feature that is unique to this entry in the Mario Kart series: the two-person karts, hence the title of the game. Two characters handle a single kart, where one character steers and the other deals with items, and they can switch positions at any time if necessary. This is the only game in the franchise where two players can play cooperatively in one kart, with each player handling a single character, though the option to play in separate 2-person karts for each player is still available. In addition, the game introduces Special Items, items that are exclusive to a pair of characters, which is another feature unique to this game. The game is one of the few games to take advantage of LAN mode via the Nintendo GameCube Broadband Adapter, which allows up to sixteen players to participate in a single race.
Super Smash Bros. Ultimate is the seventh Mario-related game to receive a PEGI 12+ rating in Europe, being preceded by the four prior Super Smash Bros. installments and the Virtual Console releases of Super Mario 64 DS and New Super Mario Bros.
While Bowser is generally referred to as "Koopa" in Japan, there are occasions where his localized name is alluded to. For example, in the Japanese version of Mario Kart Wii, the Flame Runner is known as the Super Bowser. Because all regional releases of Super Mario Sunshine use the English voice acting, Peach calls Bowser Jr. "Bowser's son," and Bowser himself calls his family the "royal Koopa line," meaning that Koopa is also his surname in Japan. Bowser Koopa is rarely directly given as his full name, but it has occurred in some officially licensed material such as the White Knuckle Scorin' album comic, as well as certain cartoon episodes and comic issues.
