Just a super Awesome game you can play your way (and this: messing with the ai story teller and the extra large amount of scenario setting on save start up & once your done with learning the game mechanics )
so either relax base building & explore & trade
either heavy survival and pressure with lot of enemmy raid and climatic event & other various event
either a mix of both
even either some totally improbable funny and/or nightmare challenge with some of the scenario available settings
there a lot lot lot (yup so so much) of cool stuff with all the events, fauna, the colonist traits to deal with, relationships, drug addiction, bonus & malus, restrictions etc., crafting, world map & etc.
So not much to say aside the fact there really a lot to do within the game with really super polished game mechanics and that you can balance thing you way, + a large mods communities on the side as well (even if personnally i play mostly vanilla aside a very few ui enhancer)
