I would use it to reward game development. Gamers make a nice juicy market of spenders, content consumer, and influencers.
The blockchain gaming model really needs to start shifting away from f2p browser and cellphone like style of games. To many view them purely as an opportunity to try and make an ROI then have fun playing those games. This defeats the purpose of gaming in the first place for the average gamer. The platform needs more spenders.
