SimCopter 64 was a game announced by Maxis at E3 1997 which was meant to be a complimentary game to the later announced SimCity 64. It underwent a tumultuous development cycle that saw it change from a simple rescue mission game into something entirely different. There were also conflicting reports from both Nintendo and Maxis about what console it would be releasing on and the level of connectivity it would share with its counterpart SimCity 64. All of these issues ultimately ended in it fading out of the public eye and being silently cancelled as no more updates were given leading up to its supposed release window.

The game was almost made for the failed Nintendo 64 Disk Drive add-on. The game would've allowed players to import their cities from the original SimCity (also on the 64DD), and fly around it. It was shown off at Tokyo Game Show, according to UnSeen64. Unfortunately, the add-on was never released outside Japan, and sold poorly in said country, resulting the game being cancelled entirely.
