WoW has no cryptocurrency implemented but an unlimited virtual currency stored in a server. While I'm interested to know if there is any game actually producing  limited cryptocurrency (with some sort of centralised and p2p combined) at its core and get it distributed through gameplay. The minecraft or Dragon tale rpg games I have seen look like they are just re-using existing currency like bitcoins and moving them around between players through casino games-like logic.

I'm talking more about a cryptowallet + miner + 3d interface and exploring-rpg gameplay all integrated from scratch including a brand new currency that can be mined only through gameplay but can still be traded through exchange adoption. The p2p system would use player embedded miners to generate currency, and each block generated would not go to the players but distributed in the game world, each coin would contain a randomly generated coordinate string within the game 3d space limits and all coordinates would get published in real-time, so everyone has a chance to target a specific location convenient to them, to fight all the mobs and terrains problem and acquired the coin that will go to the embedded wallet.

Profit would be generated by % of currency generated to the game owner. And all sort of incentive can be applied, like faster % character movements if you provide better mining speed with your rig and so on.

Plus all rpg like I have seen are quite poor in term of graphic and gameplay, I mean to create something that gets closer to games like Skyrim, and a gameplay that it's not casino like, but real rpg-style exploration.

From there, players can trade in game for specific power ups that improves the chance to fight obstacles faster, they can trade coins offline using just the embedded wallet connected or perhaps a companion ios/android app just with the wallet features like blockchain.
