For this to happen you need the game publishers to sign on board. Currently the only one that is working on anything is UBIsoft and they are going to keep it as a private centralized blockchain that they can control

We need a new blockchain/coin to be created for this purpose and ICO it. Than you have to use the ICO money to bribe small publishers to get onboard.

We all agree this needs to happen but no money/talent is motivated to see it come to life.
