So one of my younger friends has this Youtube channel (which luckily hasn't been deleted) where he has showcased this game that hasn't been commercially available for almost 12 years1. He is able to do this only because he has a device which still has this game after around a decade.[note 1]
Now, while there are only three videos of the game that he has uploaded, I wonder if there can still be a copyright infringement problem caused by these videos.
I feel like this would be a problem if the company that originally made the game brought up a lawsuit against my friend. This could probably happen because the game is not commercially available, so technically (although I don't really know) it could be illegal to own a copy of it.
So my question is: Is it illegal to make videos showcasing games that are no longer commercially available, or am I just overreacting?
Notes
[note 1]My friend originally got the game through legal methods in early 2012.
