Naturally, the mod isn't perfect - you may have trouble building other cities nearby, and the various starting values like pollution and land value may be misaligned, among other issues But all in all, it proves that with a bit of fiddling, it is possible to have bigger cities in SimCity. You can download the mod from Simtropolis.
Modders say it's not.Ī new SimCity mod called Project Orion extends the possible boundary of your city to 3km - about four times the default size. Maxis said it was a technical limitation. SimCity sets strict boundaries on the size of your cities, something longterm series fans found very disappointing.
