Originally based in Berkeley, California, the company was moved to Renton, Washington, in 1997.

Products include Cyberpunk 2020, Mekton Zeta (an anime RPG), Castle Falkenstein (a Sorcery and steampunk RPG), The Witcher: Role-Playing Game (based on a fantasy series based on novels by Andrzej Sapkowski and video games by CD Projekt Red),[1] Teenagers from Outer Space (an anime universal setting, the first generic anime RPG until the creation of Big Eyes, Small Mouth using the Tri-Stat system) and several RPGS based on anime such as Bubblegum Crisis, Armored Trooper Votoms and Dragonball Z.

Its first desktop published books were Mekton II in 1987, which looked much different from products that R. Talsorian would be putting out just a few years later (such as Cyberpunk 2020 (1989)).

Despite its "major" lines being on hiatus during that period, RTG still supported three licensed anime RPG lines (Bubblegum Crisis, Armored Trooper VOTOMS and Dragonball Z) through its ANimechaniX label and occasionally issued reprints for Mekton Z and Cyberpunk 2020.

On January 4, 2006, R. Talsorian Games founded their first demo team, The Chrome Berets.
