Game DRM companies are falling into line behind OS X after Steam decided to support the operating system, and today online game retailer GOG.com is bringing over 50 titles to the Mac. Notable games include Ultima IV and Sim City 2000. Right now they’re on sale too, so you should go and pick them up. For some of these games, this is the first time they’ve ever been legally able to run on Mac OS X. Good Old Gaming is a company dedicated to preserving historic games and making them able to run on modern PCs, so this is great news for gamers who run Macs.
