With the increase of accessibility of AI for both text and art, the implications on the RPG world have been greatly apparent. I have an ongoing 5e game that I run on a Foundry server, but this can also apply to the other variety of TTRPG games out there as well.
I've used Stable Diffusion to create character and scene art and it's allowed me to output high quality visuals for my players. When I'm having a hard time getting out the words I want to say, I've pulled up ChatGPT to help me convey the ideas. I've also used ChatGPT to fill out random encounter tables, come up with names, and fill out towns for flavoring. There's still a lot of work involved and I only keep about 5% of anything that's generated, but I feel like this is a tool that has helped me become a better DM rather than outright replace me entirely.
The "Create a Track" feature in Stunts BLEW MY MIND as a kid! I loved that game
