There is no supply of physical copies for the original nes zelda. Used copies have nothing to do with nintendo and do not set the price, especially since the actual carts sell for way more than $10. Charging $10 for a digital download of a 20+ year old game is rediculous. If u think its a fair price, u are entitled to your opinion, but the words "digital supply," what even is that? There is no limit to digital copies... what "supply?" Nintendo doesn't have a market for physical copies of NES games either, thats 100% used copies and collectables. This is not supply and demand, Nintendo simply decides what they want their price to be and that's that. Notice how the price of VC NES titles hasn't gone down at all? Or up, for that matter. Plus, how do you know enough people are buying it to warrent any price? Do you have Nintendo's sales figures handy?
