Systems are small, expectations low, challenges firm.
I very seriously enjoy the retro scene today. It's possible for ordinary people to participate, even make games others will play and pay for. Homebrew.
Completing that experience was one of those life checklist things. I had a great time and have learned a lot and was able to explore games on a technical level in an achievable way.
Personally, I see this being cyclic. The big names and players will always be there. But little scenes pop up regularly, and those are a treat for those who go looking.
