This would lead to every game to try their absolute darndest to waste as much of your time as possible. Not just with a high amount of cheap repetitive content, but also through tricks like slow menus and unskipables intros/transition for everything. I bet some devs would go as far as making loadings longer on purpose.
It would drive me fucking nuts.
Maybe my first post was easily misunderstandable. I'm not telling that the only measure MUST be the game time. Try to imagine your scenario with an user score implementation. Lot of people that complain about this cheap trick to improve gaming engagement could be an added feedback for Microsoft.
