Okay, so when I played through the game originally, I only sought help when I got stuck. I made it through to the end with only missing 5 achievements (yes, I am on 360). I think that's pretty good.
However, as soon as the end credits finished, I started a new game to get the achievements I missed. What I didn't expect was to see things I never saw before (aside from the things connected to the achievements).
So far, I witnessed a robbery, found an enchanter I never knew existed (behind a shrine), and a wishing well that I never knew existed. I am even more glad I decided to do another playthrough and hope to find more new things.
I am sure I am not the only one to experience this, right?
