For a game called Mario Tennis, Mario Tennis contains shockingly little Mario Tennis. Instead, what's here is a fully fledged tennis based RPG where you take control of a pair of original characters who join a tennis academy in the Mushroom Kingdom, and it's as awesomely weird as it sounds. Mario and crew are treated like celebrities in-game, and your goal is to work your way through the ranks to face off against them. I just described Mario Tennis: Power Tour. Go play it.
