Carl and Richard talk to John Sonmez about MonoGame. MonoGame is an open source implementation of the Microsoft XNA 4 framework for building cross-platform games. How cross-platform? XBox 360, Windows, Mac as well as iPad, Windows 8 and the phones - iPhone, Android, Windows Phone. That's pretty cross-platform! The conversation digs into the skills you need to build games, whether these tools could be used to build non-game apps and more.
