These models are like filling the pockets of game owners only. I think they are making entire tokenomics for their brand just because initially they will get investment through ICO's, pre-sales etc. Using that money they develop the games (??) and definitely there is so much money is raised they do not even consume that much.
They are already in profits and just keep running the games for some extra bucks or regular pay-check.

If they started using bitcoin right form the beginning then they don't have anything to offer except traditional way of getting users on board to invest in their venture and gain little capital.

However, these days peeps are keen on investing into tokens because they think it could be next bitcoin and they could have loads of profits in the future. Unfortunately it's the want and greed of money and nothing else that pulls the crowd these days.
