They're going multiplat because the system isn't selling. Anyone claiming that putting games on a sub will literally harm game design and create Netflix only shovelware is the one gaslighting. See Indiana Jones, Fable, and Gears, let alone Doom or Call of Duty. They're all going to be on a sub, and they're going to be on cloud, PC, PS5, Xbox, GP. The issue of a game being big budget like Endgame is not related to the sub at all. It's related to the actual studio's history and what they're individually capable of. Double Fine, inXile, Undead Labs, Compulsion, Obsidian, are not going to be making top tier "Endgame" AAA games because they aren't capable of doing that and they aren't even trying to do that. They're AA studios.
Nintendo also has AA studios it works with extremely regularly and puts out many AA games like Echoes of Wisdom recently, or Laughing Man.
I think the confusion about this "Netfllix" stuff really originates from Sony fans because they really don't have any AA games at this point. They are all in on only AAA, and so people think that if it's not that, it's a failure of some kind.
