I didn't skip cutscenes. Started on the early-access launch (Friday), finished it around very late Tuesday (Wednesday 3am). This was with me going ham on it on Saturday and Sunday. Mondays and Tuesdays I didn't get to play much.

If I had no work, I probably would have ended it early Tuesday.

If I had skipped the cutscenes and everything, it probably would have taken me less than 2 days, yeah. Don't see what the point of doing that is. The story is a huge part of the game. Playing without knowing what is going on just feels... meaningless.
