It is most definitely Apple's fault. There might be a chicken-and-egg problem, but it mostly stems from Apples really poor support for backwards compatibility.

It is most definitely Apple's fault. There might be a chicken-and-egg problem, but it mostly stems from Apples really poor support for backwards compatibility. There's been a few times when it seems like mac gaming could be making a comeback only for something like 32bit support to get removed. Rosetta will not be around forever, and when it goes, game developers for the most part won't be rebuilding their old games for a new platform. The lack of good high performance graphics also deters "serious" gamers, and gamers are generally trying to get the most performance out of every dollar, which is just antithetical to everything Apple.
