Year of Publication: 2018
Publishing Company/Creator: R. Talsorian
The Witcher is a fantasy RPG based on the novels by Andrzej Sapkowski (and maybe also the video games created based on those same novels). The game uses R. Talsorian's Interlock system (used in other games, such as Cyberpunk 2020, Mekton, etc.) R. Talsorian had not created a new RPG in quite some time before publishing this RPG, and so the Interlock system has seen some changes in this incarnation, and likely informs the work being done on Cyberpunk Red.
