Sounds almost "too good to be true", and when that happens... it usually is. There are so much gaming projects already!
There are a lot of gaming projects in general, but you should agree that this one is unique in crypto world. Not only they already have a working platform, they also have a huge community of users.
Droxne is another project that is based n mining the tokens while you play, but the problem with that idea of theirs is that it will only work in their mobile games, not in playing whatever game you want; Playkey, uses the power of gpus in a different way, providing computational power to a cloud-based game hosting, which each server own by a group of people sell, the problem is that they will need a server for the beginning of the service, because there wouldn't be many people getting into this, later on, when the servers and the demand increases, more people will get to share their gpu power, so is kind of a gamble, and it depends on the marketing of the service, the adoption of cryptos, and the increase of the demand for cloud gaming.
