You are right op, gaming is a billion dollar business. That is why I think there are already projects venturing into gaming and blockchain. Hash rush and Lordmancer are games that will have their tokens in eth blockchain, but it is not like your idea. Someone will surely go into that someday.
I believe the only blockchain fit for this industry is Ethereum. However, eth is still young and a lot of missing features are still under development.
The structure of the Ethereum blockchain is similar to Bitcoins, in that it shares the record of an entire transaction history, but what makes Ethereum different from Bitcoin is different is that it features additional applications, such as smart contracts and crowdfunding.Ethereum takes a fresh new look at blockchain technology by taking the fundamentals of cryptocurrency, and expanding that thinking and applying it to a larger scale. With the technology so young, were just now fully understanding the potential and realizing what applications could be created in the future. Yet, Ethereum shows great potential to decentralize many of the worlds day-to-day operations through a technology that is vastly different from whats been used in the past.
