This game crosses most of the Sega icons and puts them on one great spin-off. The graphics are decent and it's pretty good for a tennis spin-off. I would recommend that you buy it if you have some spare cash.
It's a bit of a yawn that ends up feeling like a barely good enough cash-in. The environments and characters are largely well-done, but the control scheme and dull mini-games drag SEGA Superstars Tennis down.
