The Old World is one of seven worlds on the MRT Server. It is the oldest world of the server, opening in July 2012.
The center of the Old World is Spawn City. Every MRT line passes through Spawn City except for the MRT Orange Line. The only city on the Old World which has a New World city rank is Arisa, which was honorarily promoted to Premier in 2015.
ATTN: This needs editing
As with the New World, the Old World was launched with MRT Lines to encourage town growth throughout the world. The Red, Yellow, Green, and Blue lines were built by Frumple prior to the official opening of the server, and the Orange line, which was built by Chiefbozx and Just_Robinho, completed construction on December 30, 2013. The lines used v4.1 to v4.3 of Frumple's MRT design. All lines apart from the Orange Line have stops in Spawn City.
