What an experience! I loved every aspect of it ans achievement hunting is pretty straight forward. There are 3 or 4 missable achievements so I suggest checking a guide for specifically avoid to miss them, they are not really spoiler (except for one, but the guide on Steam is ok in that sense).

Finishing the game doesn't stop you from keep on exploring, so one play through is enough to get 100% (as long as you don't miss the missable).

I just suggest everyone to play the game and go for the 100%.
