I found another TTRPG that’s good for this! The game is called Twilight 2000, and I’m specifically referring to the 4th Edition of it. The default setting is a post-war year 2000 involving the Soviet Union not falling and launching WW3 in the 90s, but much like Endure it can be modified to handle other settings as well. I’ve seen games based on Y2K, Brexit, EMP strikes, and video games like The Division, The Long Dark, and Escape from Tarkov. There is a bit of a military and/or combat focus to it, but also stuff like Home Bases and travel rules. It also comes with solo play rules, so you don’t even need someone to run it! I created my nuclear family as Player Characters in the game using its Lifepath system, and I intend to use the system to run a series of crisis simulations for entertainment and educational purposes. I could also do something similar for the community here the way I tried to with Endure, but since Twilight 2000 is not only a system with combat but also a lethal system it’d have to be known ahead of time that your characters could get hurt and/or die. Let me know if this is something anyone here is interested in!
