OCModShop published a review of the Sega Superstars Tennis available on Nintendo Wii and DS, Sony PS3 and Xbox 360.

Quote from the review: "Wii players have been crossing their fingers that Sega Superstars Tennis would be the answer to our tennis itch. A fun, interactive, accurate tennis game would be to die for. Does Sega Superstars fill the void? Eh kinda. Sega Superstars Tennis is essentially Mario Tennis with Sega characters and more mini games. Unfortunately for me, I hardly know any Sega characters except for Sonic, Tails, and Monkey Ball dude (see I dont even know his name.Sega loser). Its not that Im a Nintendo snob; its just that Sega characters arent as well known to the average gamer. The fact that this game has Sega in the title probably doesnt bring it any more attention."
