When Dungeons & Dragons popularized the simulation of characters in games, it entailed that players fill out quite a bit of paperwork. Characters require a record of their names and ability scores as well as their dynamic attributes like equipment lists and hit points. As a way of preserving the state of the game for each player, the character sheet thus became an essential accessory in role-playing games. But before characters, there were similar record sheets used in some types of earlier simulations, and their continuity with the later Dungeons & Dragons accessories is immediately apparent upon inspection. Above is a sheet that shipped with Gygax and Arneson's first collaboration, the naval wargame Don't Give Up the Ship (1972).
