hello @bitcoinflood,
I think the gaming world is very big and epic not to mention that gaming is a billion dollar industry, for now games that pay coins are not very common but eventually all games will be paid in coins and this will drive more coins.

publicity note:
I'm promoting That curation trail on HIVE and it would help me a lot if you forward it, You can also check it yourself: you might find it interesting to join, I'd love to hear your comments.
