I think there should be things like hunger, thirst, tiredness, dizzyness, cold, wetness and similar - that would add realistic restrictions on how far you can go on exploring the world.
The good bit is as this - if you never get tired (like now), you can just go trough the entire map in one day, and the game is not sa interesting anymore - or at least, not medieval. If you never get tired, it\'s like the modern world, you just drive whereever you want to.
If you did get tired, your effective range would be limited, at least at first, and you would have to do things in your close proximity - that would make you hang out in a bunch you live close to and such.
I think having sets of small-ish commmunities is a good idea [tm] for this game. of course it won\'t be like what we are used to on the net, but it will make the game more interesting.
