Etter Google Stadia-avsløringen skulle man tro at Microsoft ville være litt nervøse, men i stedet virket de ikke spesielt imponerte, og var snarere mer selvsikre på at xCloud var på riktig vei. Det mener de fortsatt, og de har jobbet med å sikre at denne tjenesten skal støtte så mange spill som mulig.
Microsoft har afsløret at tjenesten allerede støtter over 3500 spill.
"Today you can play three generations of amazing games on Xbox One. That means that Project xCloud has the technical capability to stream more than 3,500 games, without any changes or modifications required by a developer. In other words, developers will be able to dramatically scale their existing games across devices, with no additional development, no additional code base maintenance and no separate updates. When a developer updates the Xbox One version of their title, those updates will also apply to all versions available on Project xCloud without any additional work."
