Then again, not all of that time might have been spent actually playing. Perhaps that user enjoyed music from the game or left it on and running for some other reason.

I’ve got numerous games on Steam which have massively over reported “play time” because they are the type of game I leave running in the back ground and hop in between (or sometimes during) meetings. Rimworld is a great example of this.

Remember, this assumes they started playing on day 1 of its availability on Stadia which is most likely not the case.
