As the resident cryptocurrency nerd at PCG, it fell to me to try and make some sense of what all the blockchain for gaming hype is about. There were a couple of sessions today on cryptocurrency in games , with the subtext that this is a new approach to virtual world economics. I spoke with a few of the people involved, and here's what I learned.

One of the difficulties with games on an international level is figuring out how to accept payments from all the various currencies. Platforms like Steam handle most of that for the developers, but what happens if you want to build in ways for players to perform trades with each other—and specifically, trades that have some real financial value? Player one in the US wants to receive dollars, not Euros or Pounds or Yen. Player two in the UK wants to pay in Pounds, not Rubles or Pesos or Won. What if you could facilitate all transactions with a third currency? That's where cryptocurrencies come into the picture.

It's not just about trades and transactions, though. Another purpose for using cryptocurrencies built into a game—or a game engine—would be to potentially acquire more players. The difficulties of getting your game noticed in the Steam marketplace might be alleviated by paying people to play your game. It's the next step in free-to-play: get paid to play! You can even create contracts so that players don't just need to install a game, but they need to accomplish certain goals: play for a certain amount of time, reach a certain level, or find some special item. You could incentivize people to keep playing. Obviously there still needs to be a way to monetize things beyond that, but whatever. (Yeah, that's a big whatever.)

It's no simple matter to integrate the blockchain technologies into a game, and it needs to be done in a way that actually makes sense—in the game as well as in the real world of money. On some level, developers as well as players would need to get up to speed on how to acquire, trade, and spend cryptocurrencies. I'm very skeptical of whether most gamers even want to learn those skills.

I have a bigger concern, however. Even if we can get the base infrastructure in place, what would we do with it that we can't do with normal fiat currencies? (That's how the crypto world refers to USD, GBP, EUR, AUD, CAD, etc.) If there are large financial transactions of any form taking place, or a large number of small transactions, you can bet the regulatory agencies for the governments of the world will want to be involved. That takes us back to square one, and possibly even worse.
