Will the game support multiple platforms?
Yes! Windows will be the first platform, since it is currently the most common gaming platform, but the series will later cover (at least) Mac, Linux, and Raspberry Pi. Portability will be a major topic in the series, so all the code will be structured to demonstrate how to write code that is easy to port to new platforms.
I realize that he's promised eventual support for sensible systems, but it's _much_ easier to write code that is portable from day one than to port something later. Everyone who's not using Windows will miss out on the majority of the project, too, having to wait until it's decided that portability is a concern.
