We can see the enthusiasm of millennial people towards the game. Many of them spend their money on a game by buying game tokens. And this can be used by the blockchain industry to enter the gaming world.
Online gaming will be huge bussiness because everyone holding smartphone that can used for online gaming. Gaming is trillion dollar industry and blockchain gaming will be a new bussiness model in gaming industry. I am believe many developers will make new project because gaming industry still at early stage and have potential for growing
To be honest the development of blockchain based game is just as you said still on really early stage. There's too much thing need to be resolved first and most of them are about networking and technical. I really think that we are still far from blockchain based gaming ages.
Howver, it seems blockchain could do pretty well in term of mobile gaming like a really light game not the demanding ones.
