I think some people here are misunderstanding his tweet. He disagrees with the comment and thinks time played is a relevant stat.
I'm here to tell you it's not, under any circumstances. The only relevant thing to the continued survival of a business is whether their products are making any money.
To borrow another user's example, a massively hyped game could sell 5mil day one and those 5mil could play it for 10mins because it's a stinking turd. Oh well, the game makers have your money, for the most part.
A game about pirates could have 35 million players and 1 billion swashes buckled, and it might sell so poorly that they need to port it to other platforms to keep it alive.
One of these was a resounding success, and the other was Sea of Thieves.
