I like when games and blockchain is togerher

looks fun
the best part is that the blockchain could really determine the ownership of in game items and make the transfer from one player to the other easier and without risks
I'm not sure how this will impact in ownership. How will it be able to check that people is installing the game on different computers?
If its linked to an account, you can easily determine on how many machine a software has been activated. The least it needs is an activation server and an internet connection
