Mario Tennis: Power Tour is one of the most addicting game Gameboy has to offer. 

The game revolves around two tennis players just transferring into a prestigious tennis academy. The two players (you choose one of them to play as) make their way through singles and doubles to reach the Island Open, the Triwizard Tournament of the game, held between four tennis academies. 

As a tennis player, the game definitely meets my standards. As you progress through the game, you earn experience points, used to level up and raise your character's stats, such as power and speed. The game really forces you to distribute the experience points somewhat evenly throughout the stats, while still raising one enough to become more than average. The difficulty can be adjusted in-game. The hardest difficulty, "Technical", is not overly challenging, but forces the user to use every experience point wisely.

The gameplay itself is on par with most other Gameboy games. The characters are slightly pixilated, but the characters move smoothly, and have the capability of 360 degree movement. There is little voicing done in this game, apart from the character's grunts while playing a match. 

The Story Itself is fairly short, clocking in around four hours, depending on how much time you spend on the minigames or training courts, and by how much you speed. However, I've played through the game many more times than i can count, to the point where I have memorized most of the scripting. 

The game overall is one of my all time favorite games on any system. Every time I play through it, it brings back memories of myself playing it when I first started playing tennis to help build my strategy and shot selection. This game should appeal to anybody looking for a great tennis game, or a great game in general.
