According to this blog entry, the source of SimCity has been released. Because the name is still copyrighted, the game is now called Micropolis, which, according to that blog entry was the original name of the SimCity project. Besides changing the code to reflect the new (or old, depending on how you look at it) name, the only change was the removal of plane crashes because of 9/11. That seems like a rather stupid move to me, but sadly it wasn’t my call. SimCity was a great game, and it holds up remarkably well. I look forward to seeing what ports and modifications the game gets now.
