I think it is in the interest of gaming producers and manufacturers in general to find new payment methods for their services. Thus, the number of clients will grow, and they will be seen as open-minds, open to new challenges.
But at the moment, Bitcoin can not be used as a means of payment for games because the Bitcoin trading process is not as easy as paying with the card. Bitcoin will be an alternative payment method in the future, but until then it needs to improve its system and make it easier to use for all categories of people.
