Everyone has such great suggestions, I'll just roll under my rock.
Speaking of a rock, that's what I believe in! I am a true adventurer that loves action more than just clicking on everything on your screen. It's already been brought up in other posts that you should still keep the world alive with so much interactivity. That's right, your game has so many items that can be moved around, no one really knows what to expect. I think you should keep it that way and have alot of hidden secrets.
The reward of finding something extra is a treasure in itself. <img src="/ubbthreads/images/graemlins/party.gif" alt="" />
