This book bundle contains a collection of ebooks in PDF format on a wide variety of game development topics that aren't often covered. Everything from Pixel Art, to Substance Designer, to gaming history, world building and game design, to C++ programming and AI. It also has one of the single best $1 tiers I have seen yet in a Humble Bundle.
