This is one of the best computer games ever made and it's great to see the Mac OS X port and the continuing minor improvements.
This is beginning to remind me of tabletop wargaming systems, that live on and are played for many, many years - sometimes even after the demise of the companies that published them.
Myth 2 for Mac can be found in many bargain bins for $10 or less. It continues to be a bargain even at the $15 full-retail price at Amazon or other stores, especially since you will soon be able to get all the scearios from the original Myth game from Project Magma, too. Not to mention all the incredible fan-created solo scenarios and multiplayer maps. The free, fan-created total conversions such as World War II, Civil War, "Pirates" and Sci-Fi and even such things as lego soldiers and little green army men - the quality of these add-ons is a tribute to their designers and allows nearly infinite variety of play.
The Myth series is not for the hack-and-slash crowd. Sure, you can bull your way through most scenarios and there is plenty of fun to be had watching things blow up and fly across the map in bloody bits. However, really fine mental exercise is in store if you take the time to learn to use formations, tactical synergy, maneuver, and terrain.
Computer games are finally reaching a level of maturity in their execution that changing technology does not require that masterpieces like Myth need to be abandoned. I'm looking forward to seeing Myth continue to provide excellent competitive experiences and solo / cooperative challenges.
