Yesterday, a Maxis insider revealed that servers aren’t required to run SimCity computationsand that offline play is entirely possible. It was also discovered that SimCity will continue to run without an Internet connection for 20 minutes before it boots you out of game and back to the main menu. Now, a poster over on Reddit claims to have accessed the game’s debug mode, which has allowed him to customise the freeway layouts outside of his city’s plot. Whoopie. The bigger news is that he also set the game’s built-in twenty minute offline timer to infinite, which means he basically made his city playable offline. No region features or saved games obviously, because those require online social elements and server storage, but still: he could build an entire city offline.
