Wonder no more because Sega Superstars Tennis brings everyone's favourite hedgehog - along with almost every other mascot from the past two generations - to the tennis court.
The characters include AiAi (Super Monkey Ball), Nights (Nights into Dreams) and, of course, their main mascot Sonic (Sonic the Hedgehog). Sega has a good track record with Tennis games with their quality Virtua Tennis series, so it's no surprise that they would try their luck with a tennis title featuring their biggest mascots. Although Sega Superstars Tennis looks like a shameless Mario Tennis clone on the outside; a bunch of mascots thrown together in a genre - unrelated to their specialties. It does everything Mario Tennis does - only better."
