I am thinking about skipping the main story from the point to which I got, namely Crossing the Chasm. The reason is , is that I would like to play the game more explorative and more like "now I want to go there, and go there and do side quests" . Etc.
But what do I miss from skipping the last part of this main story? Am I unable to enter certain area's? I read in older posts something about Coldwell silver quests? I am not sure if that is relevant today because this was a post from 2015 that mentioned this?
