At some point, it will take over. At some point, you will have games like Red Dead Redemption, where everything, from ammo, to horses, to guns, can be sold and resold through blockchain.
You will have in-game economies that can be used as real money in the real world.
This will happen, stuff where people can earn money always take off, you just need the right game, the right business model, and players need to feel they can earn real money. Once that's in place, it will become gigantic.
Like poker or slots, people just need to "feel" they can potentially earn, and people will come flocking.
In 2033, Naughty Dog will be making blockchain economy-driven games. Mark my words.
They will also have machine learning systems that builds worlds and systems 10 times better and 300 times faster than humans can do. But that is gonna come a lot sooner than 2033.
