Maxis put a hard limit on city size in the upcoming SimCity, but the studio plans to expand the maximum city size in the future, creative director Ocean Quigley told IncGamers.

"We'll eventually get around to expanding the city size," said Quigley, although he cautioned that he could not give a specific time frame for that change.

Maxis placed a limit of four square kilometers on city size for performance considerations, said Quigley — that size was "the performance constraint [the studio] decided to work under" in order to ensure SimCity could run on computers with a wide variety of hardware specifications.

"We need to keep in mind that SimCity is a mainstream game," Quigley explained. "It's not a game that is only going to run on high-end gaming PCs; it has to run in your dad's PC as well."

SimCity launches March 5 on Windows PC and will be available on Mac OS X this spring.
