The part I never understood about the concept of transferrable in-game goods is -- why bring crypto into it? I don't see how the blockchain solves any of the difficulties with the idea, either for the players or for any companies who are on-board with it.
I also don't see why any of the companies would be on-board with it, given that accomplishing it would take a lot of development effort for little reward, and the game companies are in this business to maximize their reward.
