Mario Tennis: Mushroom Cup is the second in the Mario Tennis series. It features a roster of 24 playable characters, 8 of which are unlocked from the start, and 8 courts, each with different gimmicks. Playing a lot earns exp points, which can upgrade your 3 stats: Speed, Strength, and Stamina. Each character also has slight stat variations to fit any playing style. There is also a new Racket system, where you can design your own racket and tweak the tightness and speed.
