Executive Summary

Players of complex live-service and tabletop-derived games—an estimated 25 million core users—regularly rely on spreadsheets and ad-hoc calculators to optimize character builds, but those tools are brittle, error-prone, and hard to visualize, causing frustration and wasted time. That pain creates willingness to pay for better tooling, reflected in an addressable market of about $1.5B (roughly $60 ARPU/year) and a Market Score of 90/100. You could build an AI-assisted builder that ingests rulebooks, patch notes, or item sheets, auto-parses them with LLMs into executable logic, runs deterministic solvers to find optimal builds under constraints, and surfaces those results as interactive visualizations and reproducible simulations. The product should include prebuilt templates for top titles, import/export with common formats, programmable scenario testing, and a community marketplace for sharing and vetting builds. This is an attractive moment: recurring seasonal metas in live-service games and the continuing digitalization of tabletop RPGs drive steady, repeatable demand, while recent LLM advances materially lower the engineering cost of converting textual rules into code—hence a Revenue Potential score of 88/100 and a competitive landscape rated as medium. To stand out you’ll need to emphasize explainability, accuracy guarantees, and tight UX—audit trails for parsed rules, verified deterministic solvers, and official or community-backed integrations will build trust and defensibility; monetization can combine subscriptions, premium templates, and marketplace fees. The honest challenges are nontrivial: rule ambiguity, frequent game patches, data-collection and ToS/legal risks, and the need for continual validation—these require disciplined engineering, partnerships, and an early focus on a few high-value titles rather than broad coverage from day one.

Market Opportunity

Complex game spreadsheets frustrate players — AI-assisted builder to auto-solve & visualize targets a $1.5B = 25M core complex-game players x $60 ARPU/year (global players who regularly use build/optimization tools) total addressable market with medium saturation and a year-over-year growth rate of 12% (tools & companion apps niche growing with live-service and tabletop expansions).

Key trends driving demand: Complex live-service games -- recurring seasons and deep metas push players to optimize builds and rely on tooling.; Tabletop digitalization -- D&D/Pathfinder online tools increased demand for character/build automation.; LLMs for rules extraction -- new ability to convert text/rulesheets into executable logic reduces engineering time.; Creator economy & marketplaces -- players expect sharable templates, paid builds and premium community content..

Key competitors include Roll20 (OneBookShelf), D&D Beyond (Fandom), Hero Lab (Lone Wolf), Pathbuilder / Community-built Character Builders, Spreadsheets (Google Sheets / Excel) + Discord/Notion (workaround).
