A fun tennis game featuring some of SEGA's best characters.
You start out with only 8 playable characters to choose from such as Sonic, Aiai, Nights, Amigo, Beat, etc. but you can unlock the other 8 in the challenge mode such as Shadow, Amy, Reala, Alex Kidd, Gilius (Golden Axe), etc. for a total of 16 playable characters in all from your favorite SEGA games.
In challenge mode, you complete different challenges from different games in order to unlock more characters, courts, or mini games. The different challenges vary from normal tennis games, tournaments and mini games. Some of them are pretty easy but some of them can also be quite hard.
There isn't really too much to say about the normal tennis game. If you've played other tennis games, you can pretty much already know what to expect. You can choose either singles or doubles matches for up to 4 players total and you have a choice between a variety of courts from different SEGA games. Each character also has his/her own super star power which can give them an edge for a short period of time. To build this up, simply keep hitting the ball (or scoring) until the star under your character starts glowing. Pretty much, if you like tennis, you'll like this.
There are also a good selection of fun mini games from different SEGA games as well. For the most part, the majority of them are fun. My personal favorites would have to be Virtua Cop (shoot tennis balls at targets in the first stage of Virtua Cop), Curien Mansion (hits all the zombies with the tennis balls), or Sonic the Hedgehog (grab rings while dodging spiky balls). Like I said, the mini games are really fun and probably the best part of the whole game.
Lastly, there's a tournament mode for either singles or doubles. You can play it against the computer or take it online (too bad there aren't many people online).
For what it's worth, Sega Superstars Tennis is a fun game. There isn't too much special about the actual tennis but it's still fun to play and the mini games are a very nice bonus. I think they could have used a few more old school Sega characters such as Vectorman, but the roster is actually pretty decent. Anyone who loves tennis, mini games, or SEGA's franchises/characters might want to give this a try.
