It wouldn't surprise me. I've been thinking about this a lot. For example, take the Average Joe who might hear about Bitcoin and decide to give it a try. Maybe he is buying a video game at his local game shop, and quite honestly, doesn't care if anybody knows that he did. He sees that they accept Bitcoin, and sees it as just another payment method. It allows him to translate his hard-earned money into a video game. He doesn't really care if it's cash, Visa, or Bitcoin.

Enter these non-financial services, like online games. Now, the only way to play this game is to send Monero into it. He may not even care at all about the currency or the fact that it has privacy built-in. He just wants to try this new game his mate told him about. He joins the game, likes it, and ends up learning a bit about cryptocurrencies in the process. IMO, this is the demographic that we want to go after-people who don't even know what crypto is, but support the ecosystem built around it.  

There is only so much trading that crypto people can do amongst themselves until some become rich, some become poor, and many become jaded. We need new blood, and I think online games involving crypto have a very good chance of attracting that group.
