While this game isn't Mario Power Tennis standards, It is still a good game.

User Rating: 7 | Mario Tennis Open 3DS

After years of waiting for another Mario Tennis game, the latest entry of Mario Tennis Open releases for the 3DS. I have to say, this game is good but it doesn't match up to the GameCube's Mario Power Tennis. One of the reasons is the lack of Power Shots which is what made Mario Power Tennis a unique game. Also, the difficulty spikes in the game which happen in the Tournament and Exhibition modes. But other than that, there are good aspects to this game which includes:

The Super Mario Tennis mini-game

Online multiplayer

customization of Miis

the courts

more playable characters

the usage of StreetPass

But other than that, it is a good game to play with friends or by yourself.
