A strange thing in SimCity: If you query (Q) the RADAR at the airport, it is reported as industrial, instead of airport.
The change in box designs was due to trademark infringement- the use of Godzilla on the cover wasn't appreciated by Toho Studios.
The first version of the game was finished in 1985, but publishers at the time refused to release it because it was a non-standard game without a clear goal. So Will Wright and Jeff Braun had to found their own company, Maxis, to get it out. In hindsight, the publishers were terribly wrong and the game became a huge success.
To celebrate the release of SimCity 4: Rush Hour (2003), EA Games put a web-based version of this original SimCity game up on their website for play.
In the original DOS release of SimCity, the copy protection was handled a bit different than most games.The game gave you 3 square symbols, and then asked you to enter a City and Population. The copy protection itself was printed on dark red papers (therefore uncopyable).
