I imagine you won\'t find it so dumb when you are searching around to get a better sword at a better price, or getting paid by some PC to take out another merchant.
There are those who don\'t need to be the brooding hero and enjoy just creating a virtual society. Those people make the place much richer and deeper for everyone. YOU don\'t have to sell items, but you\'ll be glad when someone is. Besides, many of the future weapons are supposed to be PC generated, so get in good with your local blacksmith and when he comes up with a great weapon, you could be first in line to try it out.
That doesn\'t sound so dumb, does it?
