 The majority of the distribution of PC and Mac games comes via portals of digital distributors such as Steam, GOG.com, Desura and several others.With the advent of smartphones such as the iPhone and the relative ease of producing these titles many independent game developers solely develop games for various smart phone operating systems such as the iOS and the newer Android.This has also seen games being ported across to take advantage of this new revenue stream such as the successful game Minecraft.
