The Nintendo Entertainment System, a.k.a. the Famicom in Japan, debuted there in 1983 and the US in 1985. New software was made for the system until 1994 in the US and Japan (the last official release in the US is Wario's Woods, while Japan's last release is Adventure Island IV). In Europe, the system kept getting new games until 1995 (the last release there was The Lion King). The first appearance of Sailor Moon in a video game is Nakayoshi To Isho, which was released in Japan in 1993.
With one exception, not one single Sailor Moon game has been officially released outside of Japan. The one exception is Sailor Moon - La Luna Splende, which saw a European release. Not one Sailor Moon game has ever been released in the US.
Atari's last game for the Atari 2600 in the US was Moto Rodeo, released in 1990. It's unclear what the last game for the 7800 was, but 1990 was the last year for any releases, and on January 1, 1992, Atari ceased all publication (although some titles were still being developed until May 1993).
No, these aren't random thoughts. You will see in due time....
