Show HN: Worldarchitect.ai – AI TTRPG GM with rules and campaign sharing

Hey HN! I'm the creator of WorldArchitect.AI.

We built an AI tabletop RPG engine that combines open-ended LLM narrative with deterministic game mechanics (D&D 5e dice checks, stat modifiers, combat engine).

We just launched 1-Click Campaign Sharing to snapshot custom rule systems and worlds into instantly playable links. To test it out, we created a House of the Dragon fanfic AI D&D campaign: http://worldarchitect.ai/shared/t3hKKtzBKCKlvg5vCnlW_2hxwH3U...

Would love your feedback on the narrative state management and rules execution!
