Mario Tennis: Power Tour review. Classic Game Room presents a CGRundertow review of Mario Tennis: Power Tour for the Game Boy Advance developed by Camelot and published by Nintendo. Mario Tennis: Power Tour is a Mario sports game. With that label comes expectations, but to their credit, Camelot tried something very different. Unlike Mario Power Tennis for the GameCube, Mario Tennis: Power Tour is primarily a single-player-focused game on the Game Boy Advance. In fact, it built from RPG elements, putting players in the role of a student at a tennis school trying to climb their class ranks. There are also multiplayer options for those with the necessary GBA cables. This video review features video gameplay footage of Mario Tennis: Power Tour for the Game Boy Advance and audio commentary from Classic Game Room's Derek.
