its not only a prob of convert mile in km (or wow is about 15km x 15km, like a small town), is a ratio prob, i think.
if my runspeed is 12km/h 500m = 2,5min also i cross the standard HE area every 2,5min, but my prob is not connect to runspeed, but if i want to do a city with this ratio this city take up a very large part of the world.
if in my mmo i want replicate a small mediterrain zone, rome cannot take up half world.
Which is the solution, small player in the same zone? its possible change the player ratio (i just try but my camera dont work and when i enter in HE again the ratio is reset), or maybe miss something.
tks
