Now that most repos host the package, I think that including them in distros could be considered. I also wrote a text which takes 2-minutes to read and describes why I think it is a good and important decision to include them https://raw.githubusercontent.com/abakh/nbsdgames/refs/heads/master/mail.txt
I think this is a zero-cost decision and it serves much more important purposes and has a lot of more positive impact, compared to a lot of much heavier stuff commonly bundled with various distros. (the games are just 500 KBs, 90 KBs if compressed, while giving endless and varied gameplay)
If you read the text, can you tell me if it looks reasonable? Is it readable? If you have any agreeing opinion, suggestions for improvement or questions I would like to see your comment.
