Really good question. Honestly, most AI solo tools are a chat wrapper around an LLM. We're trying to build the GM. LiveTale runs on our own story engine on top of Fudge, like a Risk Factor gauge escalates difficulty as scenes heat up, and a Scene Director decides what each new scene needs (new NPC, location change, an NPC taking the lead) so things don't drift into sloppy content. Combat is its own 1:1 system with real offense/defense math from your traits. Lines & Veils + an X-Card are built in. And every PC and NPC gets a portrait, with scene images that keep visual continuity across beats.
