Flowing with the story. At **Terminal Viscosity Games**, we believe the best gaming experiences happen when the rules get out of the way of the story. Based in Springfield, Illinois, our small but dedicated studio is built on the belief that a game engine should be bullet-proof, and the player’s experience should be seamless. ### Our Story Our journey began in the fall of 1983, when a coverless [*AD&D Player’s Handbook*](https://terminalviscositygames.com/terminal-viscosity-games-blog/of-dice-and-men?hsLang=en) was rescued from a book burning by a not-yet-Legendary Bill. That single act of defiance sparked a forty-year obsession with game mastering and systems design. Today, we combine that "old school" passion with over a decade of professional experience in instructional design and IT. We don't just make games; we break down complex mechanics to create intuitive play aids, reference cards, and streamlined systems that keep the focus where it belongs—on the players, not the rulebook. We envision a future where the friction between rules and imagination disappears. By perfecting the mechanics that power play, Terminal Viscosity Games aims to set the gold standard for immersive gaming, from the technical foundations of the engine to the farthest reaches of the *Asterism Rhapsody*. #### OUR PRODUCTS [Asterism Rhapsody](https://terminalviscositygames.com/asterism-rhapsody?hsLang=en) [The Viscosity Engine](https://terminalviscositygames.com/the-viscosity-engine?hsLang=en) #### OUR COMPANY [About Us](https://terminalviscositygames.com/about_us) [Contact Us](https://terminalviscositygames.com/contact?hsLang=en) [Merch](https://terminalviscositygames.com/merchandise?hsLang=en) ![back-to-top](https://f.hubspotusercontent00.net/hubfs/7712601/back-to-top.png) © 2026 Terminal Viscosity Games LLC
