Games are so huge and help to propel technology forward. Think of the majority of time spent on a smartphone. Most smartphone screen activity is spent on games. Have a spare few minutes out comes the phone and boom they are playing a game.
These games normally cost money as they go structured as a Freemium model. They can start for free but if they would like to have any extras that help them to level up they will need to pay a small fee.
Blockchain gaming will change everything. The second people start to realize they can burn just as much time on the blockchain and make a bit of money, wow things will explode.
