Call Back/ Brick Joke: One of the bits of trivia that appeared in SimCity 3000 was that Maxis is Six AM spelled backwards. In SimCity 2013, the moving trucks all had '6 AM' along with an inversed version of the Maxis crescent painted on them.
Keep Circulating the Tapes: The Windows 95 version of SimCity 2000 is typically considered superior to the DOS version, but GOG only offers the DOS version for digital download. This is technically because it's much easier to get it running on modern computers (it simply requires bundling the game with DOS Box, as opposed to reverse engineering the entire game code), but it's still somewhat annoying.
Shrug of God: The developers of SimCity 2013 are on the record for saying they always anticipated traffic would be an added challenge in the game. Translation: "We're as stumped as actual city planners. Tough."
Port Overdosed: The original 1989 game is one of the most widespread games of the era, appearing on almost every computer platform available at the time, in addition to later console/handheld and cell phone ports.
2000 also counts, though it's complexity and relatively high requirements resulted in compromises that's the root of all the issues that got it branded a Porting Disaster- specifically, being ported to systems that had even less memory or processing power than what the base game was written for.
Will Wright developed Raid on Bungeling Bay (1984), but discovered he was having fun building cities out of the tools he was working with. Hence SimCity was born.
