Ok so you would rather Sony make a 100 dollar exclusives because if the budgets keep getting bigger they going to have to charge more for their first party ip.They want gamers to double dip. Which is also why they do director's cuts/special editions and remasters/remakes.
Going day and date would cannibalize console sales, because that's how they got people like me who play on PC but also have a PS5 for the exclusives.
