One thing about Rimworld design I'll give Tynan is that anything very consistently comes out of the box tuned to be difficult. No one feels a need to run off and grab hardcore mods or force extra limitations. Almost every mod, even the realism ones, all tend to reduce the default difficulty, always triggering the "cheat" debate. It's pretty rock solid design, even if everyone feels their own version of how it should be changed for their own tastes.
