Age 39 here. So a really old guy by this group's standards.
Lots of missteps over many years, tons of dead ends and finally seeing that changing a bit lately.
Making a ton of asset packs and quietly have gamedev stuff moving forward in the background. Had eBay, Etsy art shops / printing services for a while but those exploded so big, after a while it was impossible to keep up with demand and I had no good way to scale up so just abandoned all of that. Now trying digital product sales and it seems to be working better.
