I've actually been saying that for a couple years now... custom JSON is pretty amazing and no one seems to realize it. Anyone can post JavaScript to the blockchain and sign it so we know it's legit across all frontends.
The real value of blockchain in the context of gaming is that we can provide an unmatched level of provable ownership and decentralized development. Even the game creators can't take away the gold you farmed or the sword you found. On the dev side of things, we can create inflation to incentivize players and enthusiasts to participate in the process of flushing out the product... be it creating levels, skins, content, or whatever else.
Unfortunately it seems like a bit of a waiting game and everyone seems to be absolutely 100% impatient and scrambling while we trade sideways like this.
