Noted authors and game developers Ernest Adams and Andrew Rollings lead you through the concepts, principles, and techniques for designing an entire video game. The first half of the book gives you the necessary groundwork for creating worlds, characters, stories, gameplay, core mechanics, and a user interface. It also shows you a process by which to approach the task. The second half of the book applies the principles of the first half to the most common game genres on the market today including action games, strategy games, role-playing games, and vehicle simulations.
