As of the release of Fight Night Champion, EA Sports will no longer be including paper manuals with its games. Kotaku reports that the decision comes as part of an effort for the company to be more environmentally friendly. Instead of full paper manuals, future EA titles will include an in-game digital manual instead. Ubisoft recently made a similar decision -- just check your Assassin's Creed: Brotherhood box.
Given recent trends to 'go green,' and the fact that digital manuals eliminate printing costs, we wouldn't be surprised to see more publishers follow suit.
