But 2024 also marks another momentous occasion, one that we should honor along with D&D's release: the 200th anniversary of the 1824 publication of Reiswitz's Kriegsspiel, the game that pioneered many fundamental system concepts that would later underpin role-playing games.

Reiswitz published his Anleitung in 1824 as a training tool to instruct Prussian officers to command troops in times of war. Over the preceding forty years, a number of German authors had built complex chess variants that took the name of Kriegsspiele, but it was the work of the Reiswitz family, and in particular the younger Reiswitz, that laid the groundwork for RPGs with:

The idea of a neutral referee (Reiswitz uses the word Vertraute), the only participant who had complete knowledge of the game situation. The referee created the "general idea" of a game, and gave to each of the participants a specific character (a commander) with particular aims. Most importantly, the referee made sure that each player only knew what such a commander in their position would know.
Players use words to describe what they want to attempt to do. Player interactions with the referee took the form of written dispatches: just like an early 19th century commander, players would receive field reports from a referee (e.g. "Squad 3 reports they have seen French troops marching towards Jena"), and would then "move" in Reiswitz's game by writing a response (e.g. "Squad 3 is ordered to hold the nearby hill and wait for reinforcements.").
Dice are rolled to determine how successful players are in the things they attempt to do. When forces clash, the referee rolls dice against a statistical model to determine how efficacious riflemen, artillery, and similar armaments would be. His game had a concept that troop formations could withstand "points" of damage before they were destroyed, and the dice in his game determine how many such points would be inflicted.
