What I wanted was a game that reacted in the same way as Wii Tennis on Wii sports, what I got is a game that reacted about a second after I moved the controller. For me, a game has to be fun, especially on a system as Graphics limited as the Wii, so yeah this sucked for me pretty bad.
I was expecting this game to be just like Wii Sports Tennis, with minor changes to enhance the game... Not quite. In this game you can actually control the movement of your character, which sounds great but can be more difficult than it needs to be. Also, there's special powers each player gets that cause the ball to do numerous things, which at times can make the game somewhat "cheap." Other than that it's a decent game with some fun parts, and sometimes some fast paced tennis, but if you enjoy Wii Tennis, I'd probably just stick to that and leave this game alone.
