The problem here is two-fold:
- Demand, and
- Openness of knowledge.
If there aren't many people around to show how to do specific tasks, answer questions, and create tools to make the modding experience better, we don't get any growth. Unfortunately, that means some people have to try to help out, HOWEVER, it results in a much healthier ecosystem.
When you think about it, this is what made the San Andreas Modding community such a success. It was at the forefront of innovation LOOONG after it's release, and because of it, a lot of players still played it long after it came out. Meaning the demand was there, and with the demand came more players willing to lean in and make the game better.
I'm not saying it can't be done now, but we gotta help eachother!
