Man... "usage / monetization" is the model that gives more money and the only one sustainable in a long term.So there are a lot of different types of ways. Your whole thesis was based on only one of those cases. Obviously that doesn't make sense anymore then.
If a big AAA studio take two them it is even worst than what I was talking.
Naught Dogs doesn't have a budget defined by Sony.It will be very similar. You give a budget to a studio which they have to manage.
But your explanation on why the model wouldn't work doesn't make sense anymore.
They created projects with a budget in mind based in how much they target to sell (that will change if they need to put a game in subscriptin model losing full prices sales).
They are independent to choose what to do at least while they give profits in their finanacials.
