GFR Games is the games arm of Threat Tape LLC, run single-handed by Kevin Stallard in Atlanta. Six titles in progress across Flutter, Unity and the browser.
GFR Games is a one-person studio in Atlanta, Georgia, operating as a DBA of Threat Tape LLC. It ships small games built in the evenings after thirty years spent in and around the games industry — a trick-taking card game, a space-trading roguelike, a tower defense built with the founder's kid, a craps variant played entirely on twenty-sided dice, and two more in progress. Everything playable runs free in a browser. Nothing is finished yet, which the studio treats as a description rather than an apology.
Kevin Stallard has spent thirty years in and around the games industry, seventeen of them running Dragon Con's Video Gaming Track, where he still appears as a featured speaker. He is the sole developer behind GFR Games.
Kevin Stallard is the founder of Threat Tape LLC and the sole developer behind its games arm, GFR Games. He spent seventeen years running Dragon Con's Video Gaming Track and still returns as a featured speaker, co-owns the fan convention Nerdi Gras, and was once written into World of Warcraft as an NPC bartender after a Blizzard developer took a liking to one of his drinks. His day job is security and governance software; the games happen in the evenings, and have done for thirty years.
The longer version is on the About page, including why the games and the security work live under two different names.
Six titles. The state line on each is the honest one — the same text that appears on the placard in each game's room on the site. Every screenshot below was captured from the live build on 10 August 2026, not mocked up.
Grandma's card table, rebuilt for your phone.
They don't stop. They don't sleep. One trench, a few towers, and your nerve.
The galaxy's wide open, the ports are unguarded, and the only law is what your guns can enforce.
Craps is just odds and probability. So what happens if you run the whole thing on d20s?
The floors collapse on a timer. The audience is real. Death is a promotion.
Please carry this qualifier if you write about it. The World Dungeon is an original work. Its mechanics are inspired by the litrpg and dungeon-crawl genre — seasonal progression, an audience economy, a system voice — none of which anyone owns; its characters, places, floors and writing are ours. It is not affiliated with, endorsed by, or licensed by any author or rights holder, it is not an adaptation of anyone's books, and it is not yet for sale.
One tunnel, 8 ships. Half of them coming the other way.
No screenshot yet, because there is nothing to screenshot. The project is data definitions and no playable scene. The wordmark above is the only asset that exists.
There is no logo, by design. The mark is type: the letters GFR set in Luckiest Guy, with Games underneath in Archivo. Please set it as type or use one of the files below rather than drawing a symbol for it — there isn't one to draw.
Display face: Luckiest Guy, single weight, never faux-bolded. Everything else: Archivo. Both are free from Google Fonts.

Kevin is at Dragon Con every year — seventeen of them running the Video Gaming Track, and still on the programme as a featured speaker. If you would rather do this in person than over email, that is the easiest place to find him.
