Which latest popular games they have? I dont played for a long time, because I dont have time now, but may be Ill try this 
GTAV, Overwatch, Dota2, WatchDogs 2, Witcher 3 and so on and so on, you can see the list on web site.The games they have are very big, and those games have millions of users. I cant find more information on the servers they will use. Or will they make a partnership with a blockchain that focus on renting out servers? I cant imagine the computing power you need with millions of people playing
Just checked out the full list of games on the website, and I'm impressed by how many they have available - they even have a couple of free-to-play games.
Maybe it will eventually be the case that ordinary people can rent out their PC resources over the cloud, and be rewarded in Playkey tokens.
Playkey will provide an opportunity to rent them powerful computers. Owners of such computers can earn on this.
