The OSR, which stands for “Old-School Renaissance” or “Old-School Revival” is a movement in the tabletop roleplaying game scene that seeks to recreate a playstyle derived from the rulebooks of classic RPGs. Beginning in the early 2000s, and inspired by early editions of games like Dungeons & Dragons and Traveller, the OSR was and remains a loose-knit community of players, game masters, and publishers. While there is much disagreement and debate among this group about the exact meaning of the OSR, generally there are a few hallmarks that distinguish what makes an “OSR game”.
