Are you not worried that the fees needed to play the game will be outside of your control?

If the blocks get to full then somebody will have to pay for the higher gas limit. We saw it with the cryptokitty rage. Basic game actions would cost 1 - 3 dollars.

Of course this won't always be a problem ... but will we have blockchain based games that on some days are not playable because it's to expensive?

Do you guys have a solution for this?
