Yeah, getting a hand full of people to run through our game really helped us learn what things needed to get adjusted so that players would try it out or explore the area. As to our philosophy on detail, we used a mindset of "We will fill the game with so many references and secrets, they HAVE to find something." Though admittedly, this meant a lot of content that may never/rarely get seen - never a good fact when you are working on a time crunch. Ups and downs, I suppose.
