Mario Tennis Advance - Power Tour

Mario Tennis: Power Tour is a role-playing sports game for Game Boy Advance where players compete in tennis matches, including singles and doubles formats. Players can customize their character with a name and dominant hand, and earn experience points to level up attributes like shot power, speed, and Power Shot abilities. The story follows a protagonist who enrolls at the Royal Tennis Academy, teams up with a partner, defeats classes of challengers, and participates in the Island Open tournament, culminating in tournaments against Mario and the gang in Peach's Kingdom. Key characters include Clay/Ace as the main player character, their doubles partner, and returning coaches like Alex, Elroy, and Tori. What makes it stand out is the RPG progression system with minigames for learning special Power Shots (offensive and defensive), a rich story mode, exhibition battles with Mario, Luigi, Peach, Donkey Kong, Bowser, and Waluigi, and deep tennis mechanics like topspin, slice, lobs, and smashes.
