This has changed since original. Once you enter a zone the contents are fixed and you only get one reload attempt with chests. For more you have to load a save before you entered the zone and re-enter but again only one reload attempt. Do you want to spend your time constantly reloading hoping for the magic ultimate sword of smiting or do you want want to spend your time playing the game? If this was real life or the movie version would you enjoy watching someone constantly going back to the last scene and opening a chest again? Or would you rather get on with the show?
