content: This is a PowerPC game. Up through Mac OS X 10.6 (Snow Leopard), Intel Macs had "Rosetta," a technology for running PowerPC binaries on Intel machines.Apple discontinued Rosetta in Mac OS X 10.7 (Lion), so there is not way to run this game (or any other PowerPC binaries) without emulating earlier versions of Mac OS X, or booting an earlier version on your Mac (which might not be possible with machines released after Lion). So do not buy it unless you are familiar with these issues.Caveat Emptor.
