In 1991, DUX Software licensed the rights to port Maxis Software's SimCity to Unix. Don Hopkins, working then as a contractor for DUX, rewrote the Mac version of the game to run on numerous Unix platforms. More recently, John Gilmore, an advisor to the One Laptop Per Child (OLPC) initiative, suggested the idea to Hopkins of bringing the game to the OLPC's XO laptop. Hopkins told SimCity creator Will Wright, who was enthusiastic about the idea and got the ball rolling at Electronic Arts, the current owner of Maxis.
