I bought Miles Morales, Demons Souls and Returnal on day one. I think they are worth the price, money is losing value, inflation will go through the roof anyway... anyway you got discounts all the time, and still now the used games market exists and is a good alternative. I don't think I would play the new Ratchet and Clank any time soon, so I will just wait for the price to come down on that one (or I will just buy it whenever I have free time to play it). I don't think a boycott is necessary, it is possible to get games cheap... well, at least I won't boycott, I don't think it is an first necessity product... it is not something you need only something you indulge into.
PS: And yes, Miles Morales was not full price, but I didn't want to rebuy it with the remake of what I already played on PS4. Anyway, it was fun while it lasted.
