So, to fit the fantasy aspect of this, I figure you could pay blacksmiths to gild your armor with different metals. Granted, it adds little to no game play aspect to the game but I feel like it would take even less programing and disc space to add that function. To make it more fun, I suppose, the little pieces of raw gold and silver could be incorporated as necessary items to gild armor.
Also, for clothing, dying the cloth would be pretty nifty as well. Not nearly as important to me though.
So, thoughts? It's four in the morning so I'm bound to have missed something so feel free to fill in what I've omitted.
Cheers.
