Inserting data from video games into the blockchain is a great idea, but will not this create a blockchain of too much size?
That's one of the big problems that we've solved with Game Channels. Check out the White Paper as it explains it. The short answer is that only the most important information is stored on the blockchain, and everything else is off-loaded into game channels (a type of side-chain).
Very good work and the best of luck for your team.
Thanks!
