Removing levels to suit your lazy ineptitude isn't an idea; adding a "mall" to a medieval game as mentioned is nauseating. Reducing emphasis on travel is a huuuuuuge step in sustaining longterm boredom and failure. Creating deadzones is utterly insensible and irresponsible. Adding more stores isnt an idea. Dishonoring the classic world is selfish. Diminishing the world doesn't improve lag, it increases it; lag is a clutter issue not an overabundance of content and space.
