It isn't the newest game around – far from it – but if you're looking for a fun Mac game to pass the time in the not-too-distant future, Sega Superstars Tennis could be one to take a look at. Better yet, the first 40 pre-orders at MacGameStore will be able to get the game for 40% off the regular price, reducing it down to just $8.99.

Sega Superstars Tennis sees your favorite characters from the Sega games universe such as Sonic the Hedgehog, Nights, Jet Set Radio, Samba de Amigo and more besides. It's not exactly Wimbledon, but the console version was a fun little time killer. If it sounds like your kind of game, be sure to jump on the pre-order early to save yourself some dollars.
