It’s because these companies keep driving up production costs on their own. Their next game has to top their last. At what point do we say that graphics are good enough? Who needs these insane amount of details? Why does a game absolutely need to be 100+GB in size? Is Bloodborne not visually appealing enough? What about God of War (2018)?
Can we not find a “good enough” acceptable baseline and just work with that? This infinite growth is annoying as both a developer and a player. Like okay, ooooh, you can render each individual hair on someone’s head and they each have their own physics. Congratulations. How’s the story for the game? Ah, broken to the point of unplayable, but you pinky swear a patch is coming.
