Executive Summary

Many d100 systems (Call of Cthulhu, RuneQuest, BRP derivatives) burden players and GMs with multi-step tables, edge-case modifiers, and dozens of interdependent rolls, creating a high friction onboarding experience for a sizable portion of the estimated 8 million tabletop RPG players. New players, busy GMs running multiple campaigns, and digital-first groups using virtual tabletops are the primary sufferers, often spending 30–90 minutes on a single character or abandoning niche systems entirely. You could build an AI-driven template platform that ingests rule PDFs and community notes, extracts and codifies mechanics, and generates interactive character templates that auto-calculate derived stats, validate rule compliance, and export to common VTT formats. Combined with a curated marketplace for shareable templates, configurable house rules, and a lightweight deterministic rules engine to check LLM outputs, the product aims to cut typical creation time to approximately 10–20 minutes and make niche d100 systems usable in remote sessions. The timing is favorable: the digital tools market for tabletop RPGs is roughly $1.6B (8M players x $200/year) and industry indicators—remote play adoption, reliable LLM rule parsing, and expectations for community content marketplaces—converge to support rapid user acquisition; internal scoring gives this concept a 90/100 market score and an 86/100 revenue potential. Publishers and VTT providers are actively seeking integrations, and a focused, high-quality offering could capture players migrating to digital-first workflows. To stand out you’ll need to combine generative models with deterministic verification, a strong UX for d100 edge cases, and an early catalog (e.g., 30–50 validated templates) plus a marketplace to drive network effects; that mixed approach addresses the common failure mode of “LLM hallucination” while enabling rapid coverage. The chief challenges are legal/licensing of core text, accurate parsing of legacy PDFs, and building trust—these require upfront publisher partnerships, transparent validation tools, and conservative release policies rather than aggressive feature expansion.

Market Opportunity

Fix convoluted d100 RPG character creation with AI-driven templates targets a $1.6B = 8M tabletop RPG players x $200/year on digital tools, modules & VTT subscriptions total addressable market with medium saturation and a year-over-year growth rate of 12-18% (digital tabletop & RPG content adoption).

Key trends driving demand: Remote play adoption -- more players use digital tools and expect integrated character management; LLM rule parsing -- automated extraction of mechanics enables rapid tool support for niche systems; Community content marketplaces -- players expect sharable templates, driving network effects; Micro-subscriptions -- consumers used to small recurring fees for convenience and automation.

Key competitors include Foundry Virtual Tabletop (Foundry VTT), Roll20, OpenAI / ChatGPT (workaround), Community Google Sheets / GitHub character builders (workaround), PCGen (open‑source character generator).
