First review of a game so here i go.
This is a game that if you you like to plan your base and be kept on your toes with storyish events then its for you.
This game has soo much random events that it keeps you on your toes. You could be doing great then all of a sudden, you get a blight so no food then you get set upon by the flu so most of your colonists are tired all the time and grumpy or someone gets angry and stabs a fellow colonist. its that sort of unknown that makes you try to mini-max what you can do.
As for mods, you will find anything and everything you want. If you want to make a clone army then do it, want to go roman and fight the spartans then grab your spear.
So grab this game and see how you feel.
