Spore is a 2008 multi-genre single-player god game developed by Maxis and designed by Will Wright, released for Windows and Mac OS X. Covering many genres including action, real-time strategy, and role-playing games (RPG), Spore allows a player to control the development of a species from its beginnings as a microscopic organism, through development as an intelligent and social creature, to interstellar exploration as a spacefaring culture. It has drawn wide attention for its massive scope, and its use of open-ended gameplay and procedural generation. Throughout each stage, players are able to use various creators to produce content for their games. These are then automatically uploaded to the online Sporepedia and are accessible by other players for download.
