AI (Improviser), Game Guide (Lore Masters) and Admins (GMs)

I've read through more or less all of the content from a rules standpoint and I think I know why a number of people are having less than favorable reactions.

In a traditional TTRPG, the GM usually knows the rules, knows where the story can go, and has a general idea of how NPCs will react. While they need play the part of the NPC, they're reacting to the players within a set of guidelines which, don't necessarily need to be funny. And if you're running an Adventure Path, much of it can be scripted.

With DCCRPG, there are really three roles that would traditionally fall on the GM. First, they're running the game. Because of the no GP d20 aspect, honestly a lot of the math comes off the GMs plate, but they're still running the game.

Next, everyone wants custom tailored skills, classes, gear, spells, mobs, etc. The world of the books is reactive to the crawlers. Carl complains about pants, gets boxers he can't wear pants with. He dreams of boots, gets unbreakable feet, then gets boots. So now you need someone who knows the lore inside and out, and can come up with things that don't break the game completely on the fly. Plus they should be entertaining.

Finally, we all want funny achievements. And no one wants them at the end of a session, or beginning of the next. Now we need someone who can improvise on the spot based on things that happen in almost real time. Or is able to put them down on paper quick enough to bring up when they get to a safe room.

The best solution if the GM isn't able to fit those roles it to do it like it's done in the books. Use the audience, aka the Players running the PCs.

PCs can each give out 1 achievement per hour played per OTHER player character (never to themselves obviously). If they have an award that fits that's not a loot box (Jimbo Soup, Able to see X on your map, etc), they can call that too (subject to GM overrule). Loot box levels are determined by GM.

PCs can slip the GM a note at any time about loot ideas that come to them. If Becky's Orc lose a hand, and they find a chainsaw, Rob may slip a note saying "She should get something like "Ash's harness of awesome - allows a weapon to be mounted onto a stump. Groovy". This can also obviously mimic Fan Box Voting. Good natured and but useful trolling should be encouraged.

Finally, if one of the players is the biggest expert on the flavor of the world, utilize them as an NPC to provide in world guidance when building custom things.

It is a lot, just like this post is. But there is a lot of good here. There should be enough content on Point Mongo in short order to allow for straight up random items pretty quickly, but really, leverage the players to aid the process if you don't want to throw things out on the fly.
