I've been playing a lot of first edition AD&D, the proper AD&D, for the discriminating gentleman.
The new trick is that I make the online AIs DM it. So this is a computer game of sorts. It's awesome. It blows the doors off of modern rpgs where they just plug an adventure into Unreal 5 Engine and you run around like a murder monkey collecting trinkets carefully chosen to keep your level scaled to the adventure. You're basically a cross between the X-Men and Super Mario collecting coins. It's kind of silly, the exact opposite of what we wanted pen and paper to become.
(Though I play these too. I really liked Expedition 33.)
I spent ages "programming" ChatGPT, which is basically just devising rules to force feed it and make it properly scan an adventure module for content. Otherwise it always starts with the same scanning skill. It was so frustrating. It kind of worked, but not really. I could get it right to the edge of being fantastic, I taught it scores of narrative tricks, and it used them, and I gave it many ways to search files for content, but it would not operate without me holding its hand (cord? I don't want to consider the implications of that metaphor). It couldn't process materials independently. When I realized how poor it was at spatial problems, I gave up. I can't fix that. I really tried to get it to build a type of rigid memory and avoid narrative drift. It barely worked . . . We were so close! I've got to say though, even in failure it did some awesome things.
Now I've moved on to Grok. Yeah, Grok is far, far more powerful. It made a mockery of ChatGPT's efforts. I'm still putting it through its paces.
As an example of an impossible upgrade, there is an old system called Dangerous Journeys (by Gary Gygax) which has something like 1000 spells in it. It should be unplayable on a computer because the spells are often ephemeral and complex. It's not like having a Fireball spell. Yeah, that's there, but most of these just don't translate to combat tricks. Because of the nature of AI, these can be implemented now. I just asked Grok:
"Combine 20, select low-level spells from Dangerous Journeys Mythus Magic into this 5e module and rewrite everything to work with basic 1e rules in a silver-standard economy."
It did it easily. It had to expand reagents in the 1e universe (it added characters to the inn who sold the basics) and devise a system of fatigue points for magic users. It rolled 1e and Dangerous Journeys together. I asked it to demonstrate each spell with a narrative example from the module. It did. It was perfect. I'd paste some of it here, but this is already too long, haha.
I'm going to test it some more and then teach it some narrative tricks. Then I'm going to launch that module again and see how well it reacts to my out-of-the-box solutions and weird strategies.
I'm considering building an offline rig to run an AI that can directly store its data in a local database. The DMing power of that would be immense. Then you'd see something nuts. I need a $1500 graphics card with loads of VRAM though, maybe two. I'll consider this down the road. Maybe prices will come down.
