What opr does

One Page Rules (OPR) is an independent tabletop wargames publisher that produces two flagship free rule systems — Grimdark Future (sci-fi) and Age of Fantasy (fantasy) — each available in multiple formats spanning battle, skirmish, regimental, adventure/quest, and (for the sci-fi line) naval combat scales. The company's core offering is free complete rulebooks distributed digitally, paired with 3D-printable STL miniature files and a free web-based army list builder called Army Forge. OPR monetizes through a tiered Patreon subscription ($5 / $10 / $20 monthly) that delivers 50+ STL miniatures per month, plus à la carte digital sales on MyMiniFactory, pre-printed miniatures on Etsy, print-on-demand rulebooks and paper miniatures on DriveThruRPG, and branded merchandise via Creator-Spring. The OPR Compatibility Program extends the catalog by certifying third-party miniature creators' models — 18 disclosed creators covering 53 warbands and 500+ models — to be playable within OPR game systems, creating an ecosystem play without OPR bearing sculpting cost.

The business operates a community-led, product-led go-to-market model anchored on Discord, YouTube (weekly OPR Hangout streams, battle reports, tutorials), and broad social media presence, supplemented by convention appearances at Gen Con, UK Games Expo, and TMX. Free rules and Army Forge serve as top-of-funnel acquisition, with Patreon and campaign purchases converting engaged hobbyists. OPR employs dozens of creative contractors (illustrators, designers, sculptors, authors) and explicitly positions as a human-made art company in contrast to AI-generated miniature competitors. Recent strategic moves include an April 2026 IP licensing partnership with Paizo (Pathfinder), a May 2026 collaborative campaign with 18 third-party creators on MyMiniFactory Frontiers, ongoing faction book releases, narrative campaigns, and a live balance-patch cycle culminating in a v3.6 edition. The company is privately held with no disclosed institutional investors, parent company, or acquisition history.

Direct peers

• Corvus Belli: Spanish publisher of Infinity, a sci-fi skirmish miniature wargame. Comparable because it operates a competing sci-fi skirmish system with proprietary miniatures aimed at the same hobbyist segment as Grimdark Future: Firefight.
• Warlord Games: UK-based publisher of historical and fantasy wargames (Bolt Action, Pike & Shotte, Black Powder, Conquest) with in-house miniature lines. Comparable as an indie-to-mid-sized alternative-rules publisher selling its own miniatures at lower price points than Games Workshop.
• Modiphius Entertainment: Independent tabletop publisher (Star Trek Adventures, Achtung! Cthulhu, Conan). Comparable because it licenses third-party IP to produce tabletop games with miniatures, competing in the alternative-rules hobby space.
• Mantic Games: Independent tabletop wargames publisher (Kings of War, Deadzone) selling plastic miniatures and free-or-cheap rules. Closely comparable business model to OPR — smaller-than-GW alternative rules plus miniature sales — making it one of the most direct competitors in the indie wargame space.
• Wargames Atlantic: Independent miniature and rules publisher offering hard plastic miniatures across multiple historical and fantasy ranges. Comparable as a lower-cost alternative to Games Workshop with its own game systems and growing community footprint.
• Battle Yak Miniatures: Indie 3D-printable miniature creator listed as an OPR Compatibility Program partner. Comparable as a peer creator producing STL miniatures and participating in OPR's collaborative campaigns.
• Titan Forge: 3D-printable miniature studio and OPR compatibility partner producing high-detail STL ranges. Comparable because it is one of the indie sculpting studios whose catalog feeds OPR's ecosystem and competes in the same STL marketplace.

Others

• MyMiniFactory: 3D-printing file marketplace and OPR's primary STL distribution channel (and Frontiers campaign host). Comparable as the ecosystem enabler on which OPR's STL business depends rather than as a direct competitor.
• DriveThruRPG: Digital and print-on-demand marketplace for tabletop RPGs and wargames. Comparable as a distribution channel where OPR sells rulebooks and paper miniatures, rather than a competitor.

Broad incumbents

• Games Workshop: The dominant incumbent in tabletop miniature wargaming (Warhammer 40,000, Age of Sigmar). Comparable because it sells proprietary miniatures plus rules and operates at scale in the same hobby market OPR targets, but it is a vertically integrated manufacturer rather than a 3D-printing publisher.
