SimCopter 64 is a cancelled Nintendo 64DD remake of the original SimCopter developed by Maxis and published by Electronic Arts for PC in 1996. It’s unclear if this version for the 64DD was going to have some substantial differences from the PC one, as happened with SimCity 64. As we can read on IGN, SimCopter 64 was officially canned in 1999:
Sim Copter 64 was even previewed at a very early stage at the Tokyo Game Show. Onlookers were not impressed with its foggy, first-generation graphics and the game’s US release was soon cancelled in favor of a Japan-only release for the disk drive system.
Since then, Nintendo has again delayed the debut of the 64DD to later this year and Maxis, apparently losing faith in the viability of the title on the DD, has abandoned the project completely.
