As does Microsoft (Flight Sim, Forza Horizons, Forza, Wasteland, Hellblade, Halo, Gears and now the Bethesda suite). Just less of it than Sony historically, and on average of lesser quality (but still high) Which was also true of Netflix Vs HBO 10 years ago.
It will be a mix of models moving forwards. I am not saying sub only but clearly that is going to be big. Gamepass went from 10 to 15 million subs this year before xCloud or the new consoles and still without really hitting that first party exclusive content they no doubt will with their dev acquisitions.
We may even see games experiment with the pricing strategy routes that a lot of eastern media has gone which are mixed models. Pay per chapter, pay for ending, free but donate to dev etc.etc.
I think the 3 obvious models that will apply to all though are clear. Pay to own a particular game, or access a library of on-demand games which are funded by subscription or ads. The latter will be much more likely when cloud gaming is able to actually penetrate the market.
