Understanding Comics
The game's development was led by Will Wright and the game was a follow-up to Wright's earlier "SimCity" series; Wright was inspired to create the game by Christopher Alexander's 1977 book "A Pattern Language", and Scott McCloud's 1993 book "Understanding Comics" later played a role in the game's design. Seven expansion packs were released from 2000 to 2003, each of which added new items, characters, skins, and features.
