Just a quick thank you to Project Magma for porting and supporting Myth II on Mac OS X!
I saw a news article on Inside Mac Games about the release of version 1.5 and was intrigued. I checked eBay for copies, but decided to hold off having recently bought another game. But last weekend I found Myth II Worlds for $2.99 (!) at a local computer store and couldn't resist. I downloaded 1.5, ran the OS X installer (another thank you here!) and was playing the single player campaign 'til the wee small hours.
