yea its obvious it will be optional. And I think this is a great idea. It might piss off companies like Prima or whoever else does strategy guides.
But if it has an in game strategy guide then they can make things harder cause if you can't figure it out you can always go and turn on the help thing to show you what to do. And be nice to not have Navi yelling "hey" all the time to tell me to go do the main quest when I'm off exploring or doing sidequests
