The differences in using the walkthrough for the xbox play, are minor. I've completed it once, now exploring everything more then I did the first time and kinda browsing the walkthrough to see what I missed. I would suggest making a save game before you go past a point of no return, in case you want to go back and do something. Just remember, the treasures you find are random and if you go back and play it over, you won't get the same stuff.
