I took a class on nonviolent protest in college. Covered the lives and work of ghandi, MLKJ, thoreau. Very enlightening.

Is combat focus a deal breaker? If not: Faster Than Light Volcanoids (early access) Darkest dungeon (kind of) Xcom

If you step away from the ship, things like mass effect and outer worlds come to mind. If the ship can be a base there’s a whole world there. Astroneer, planet crafter (early access), Starbound, terraria, Subnautica If exploration/colony sim is cool you’re looking at factorio, rift breaker, frostpunk, ixion (hardcore!), satisfactory

I expect I’ve stayed from your prompt at this point. It’s a tough niche. Good luck with your search!

Edit: on mobile, don’t know why my line breaks didn’t work. Forgive the formatting.
