Things change when they're rare...but like max I've sold something for was still less than 2 silver.
Hmm, well, hopefully the finished game has a better economy system.
More reasons to purchase things, as well as the ability to hold more than one stack of something.
Also, if different towns offered different prices, that would be nice.
And if they sold different things too, maybe some trade items.
So that if you happened to lump it from one town to the next you could make a bit of cash doing so.
