can i play it on mac?

I don't know, but it's likely only for Windows. There are some third party apps that allow you to run Windows programs on your Mac, like "Parallels" or a hard drive partition Boot Camp (which you'd need a Windows OS copy to install). A game like Panzer General 2 has relatively low tech requirements so you could probably get away with something like Parallels, which would not work well for modern, high-demand games.
