Around September/October 1990, Nintendo Power magazine announced that they would bring the highly acclaimed Maxis game SimCity to the Nintendo consoles on the market at the time, both the SNES and the NES. The magazine listed a release date of this for simultaneous release for Spring of 1991. In the November/December 1990 issue two screenshots from the game were published and those two screenshots were for a very long time the only proof that a NES version of the game actually existed.
Almost 15 years later, Nintendo Power addressed the unreleased game once again, reffering it as “A lost treasure of the past”. Shown in the screenshot below, they say the game was never released “because of bad timing”. It also states the game was “far in developement” yet unfortunately “canceled”(Nintendo power made a spelling mistake there XD)
Thanks a lot to NES World for these screenshots!
