"NVIDIA's GeForce Now game streaming service has been a bit of a hit and miss lately, with some of the bigger publishers like Activision-Blizzard, Bethesda, and 2K games revoking availability of their digital game libraries on NVIDIA's service. Possible reasons for those events were unknown and the platform did suffer from it. "
"However, it seems like there is no end to the pain, as some other very big publishers decided to revoke their digital libraries as well."
"Big names like Microsoft Xbox Game Studios, Warner Bros. Interactive Entertainment, Codemasters, and Klei Entertainment have all decided to stop offering their games on the GeForce Now game streaming platform."
