People already had a lot of fun with AI Dungeon 3 years ago, arguably more than a lot of generic video games which deliver the most basic plot imaginable. I am certain than AI gaming will at least become its own popular genre in the near future, and probably permeate the rest of the market later.
Also, modern chat AI can simulate a DM very well, they even know about the rules of most tabletop RPGs. I recommand to try it, it can lead to some very creative outputs.
