I agree, sales are constant (at least on PC) so I almost never even paid the $60 price tag. They can keep cranking up the prices but more and more people may just wait for sales. I know Nintendo games don't go on sale very often but that makes the ecosystem even less attractive. $450 is in the range of a Steam deck.

Inflation or not, prices can only go up if the market will support them. If people are unable (or unwilling) to pay the higher prices, then prices basically can't go up.
