I do agree, cloud gaming has massive potential if they get it right. I haven't personally tried any of these services (nor have a need to, since my 1060 is still serviceable for all the games that I play), but the price point at which they are offered does seem quite attractive.

Although I also think that over time, the prices for these services (especially the most successful ones) will increase significantly once they've got a large user base. Right now, cloud gaming is still not that huge and they're most likely taking losses to gain a large user base. It'll be interesting to see how this sector unfolds over time.
