Mario Tennis for the Game Boy Color is a unique experience compared to its N64 counterpart. The GBC version features an RPG-style world that lets you progress through the ranks at the Royal Tennis Academy, allowing you to work your way up from Rookie to Master. As you play through the main mode, Mario Tour, you'll gain experience points by completing training programs and defeating other students, boosting your tennis stats in the process.
Mario Tennis also offers a more relaxed pace outside of gameplay. When not playing, you can explore the Academy grounds: talk to other students, or simply enjoy the surroundings. The game includes an exhibition mode for quick play, either singles or doubles, as well as support for the Game Link Cable for multiplayer against a friend.
Mario Tennis was released on January 1st, 2000, and is a sports game that provides a fun twist on tennis. The GBC version's unique blend of RPG elements and tennis gameplay makes it an interesting take on the Mario franchise.
