I was thinking something like Factorio or Rimworld that can be a very slow paced difficulty without using bullet sponges.
Defeat could be the result of hours of just barely clinging on and finally collapse. Rimworld lets you reload or change difficulty, Factorio usually you get a decent enough idea fairly early on as to how hard it will be and if you are going to struggle then that is clear within the first 20 minutes or so of a game. Generally neither game lets you get 12 hours in easily and then you are stuck at an impossible wall outside of big mods or some very custom settings.
