So, gaming on the Mac has never been a huge thing, and the jury is out on whether Steam will change this long term with their support of the Mac. I wonder what the AppStore has to offer in this rather large segment of customer entertainment purchases.
I'm not suspecting (at least not yet) that the AppStore is fitted to replace such a tailor-made applicaiton such as Steam, but no one doubts that the AppStore is what made the iPhone the worlds most popular mobile gaming unit. It has great potential for small developers to reach a huge market.
And the Mac is a huge market, and adoption of new OSX versions is also off the charts historically, so will small type games on the Mac App Store be the next gold rush? I can see games such as Peggle and Bejeweled and an assortment of tower defense games being ported directly from the iPhone. After all, the iPhone developers (which I'm sure outnumber Mac developers these days) already know how to program for the Mac more or less.
This doesn't mean that Grand Theft Auto 5 is going to be released for the Mac, but I have a feeling that these small type games that have seen a tremendous leap in popularity the last few years (thanks to Pop Cap games and also the iPhone) could potentially be dominated by the Mac on the desktop.
