"The Special Games mode in Mario Tennis Open lets players hone their tennis skills while enjoying tennis games with a Mario
twist. Players can check out games such as Super Mario Tennis, which puts a classic Super Mario Bros. twist on tennis drilling.
As they play through familiar game levels, they can use their tennis swing to stomp Goombas, and Koopas along the way.
People can play as their favourite characters from the Mushroom Kingdom or even compete as their Mii characters. They can
also customise their Mii characters with Mushroom Kingdom-themed tennis gear, which not only enhances players' appearances
but also can boost their stats. The wide selection of available gear includes Bowser's favourite racket, a Bullet Bill outfit
and Peach's tennis shoes. In addition to a singles tennis match mode, another mode in the game lets up to four players
compete online in multiplayer doubles matches. Players can also compete online for leaderboard standings in the Open Match
mode. Whether playing with other Nintendo 3DS owners in the same room or against distant competitors using a wireless broadband
internet connection, players can cooperate to take on a common opponent or stay competitive and try to claim the glory for
themselves. Players can opt to use intuitive touch-screen controls or increase their strategic options with traditional button
controls. They can also switch seamlessly to the Nintendo 3DS system's built-in motion controls."
