This is just such a weird game design choice, but it is one of the few times I've seen blockchain integration with a digital game actually applied to something that almost makes sense. De-localising the database storage for objects and object management, effectively requiring two factor authentication for any sort of object manipulation, could definitely be of some use if you expect the gameplay to be focused very heavily on loot and loot training.
It's mildly concerning that there isn't any discussion about what the rest of gameplay is supposed to be like, either in this article or in the video from the creators. When people talk about a game without actually talking about the user experience of the majority of play (as one would expect), it generally says that the action of the game is not the primary concern beyond what's being talked about.
That generally ends poorly.
All that said, this does, at the bare minimum, perk my curiosity and I admit that I am slightly intrigued.
