I wanted to ask you, dear editor friends; if it is possible to register video games that have been "unofficial" personal creations.
there is the case of "Star Trek" by Tatung Einstein, which is not an official video game, but rather the creation of a publisher and collector.

I would like to know your opinions.

Yes. All games are welcome here. In fact most of the early 70s and 80s Star Trek games are not official licensed games and were done by fans.

All games welcome. You are even encouraged to make your own and enter them at UVL:
