I can't say that I'm a huge fan of Feral Interactive: They're a company that specializes in porting games from other platforms over to the Mac, and I'm more interested in natively developed and published Mac games. But I have to respect them nevertheless: Feral picked up an Apple Design Award for their port of Deus Ex: Human Revolution at WWDC last week, so they must be doing something right.
And now Sega has chosen them to bring Sonic the Hedgehog to the Mac platform for the first time. Feral is going to be bringing Sonic and SEGA All-Stars Racing and SEGA Superstars Tennis to the Mac App Store, with both games arriving later on this summer. In addition to porting the games, they'll also be Game Center-enabled, because Game Center will be used in Apple's next OS X update, Mountain Lion.
It's also interesting that Sega has already released one of these games, All-Stars Racing, on the App Store. So Feral can probably thank the iOS platform for Sega's interest in Mac gaming. I wouldn't be surprised if it's because of Sega's success on iOS that the company is dipping its toe into the Mac App Store as well.
