RimWorld sans mods is a great story teller:
My play allowed me to build a big colony within a mountain like in dwarf fortress, then I woke up an ancient terror like in df, but something unexpected happened when two of the remaining settlers, a kid and an old lady where able to escape.

I got them to escape the map, then resettle with almost impossible odds, with just the shirts on their backs, no food, tools nor weapons and the kid's just a kid.

Fast forward some odd 20 hours, their tribe was able to come back and re-take the base.

Which is something I've never seen in DF.
