The only reasons why I hesitate to give it a full "5 stars" rating are the bugs and some bad game design choices. Having said that when you develop a game on THAT scale I guess the two issues are kind of inevitable. The scale of this game is massive and most of the game breaking bugs have been addressed by now so thank the poor sods that had to brave their way through early access :P
This is the closest thing to pen and paper experience currently available out there. Highly recommended!
Give it a go and you'll be fine. Save a lot (be generous with the amount of auto save files in the settings) and don't hesitate to ask uncle Google for help if you get stuck.
Feel free to watch a couple of "X things I wish I knew..." videos on youtube and you are set!
You will love this game!
