That may be true for many, but I'm willing to bet most of those "hours" they count are for GTA Online. Have they ever mentioned what percentage of players play Online versus all sales? Because that is something many of us have never and will never touch so it isn't included at all in my value consideration other than a negative for the company to focus on INSTEAD of additional single player content.

If they want to turn GTA into an always online Game as a Service, that is their prerogative, but don't try and hide it stuffed alongside a single player game they'll ignore after release, and don't be surprised when some people stop buying and playing when the only option is online multiplayer.
