At the beginning of this generation, I planned to buy a used PS5 when the Pro version was coming. I did not know that the PS5 would have almost no games for me (especially because they released the big ones for me on PC), the base PS5 would cost even more, and most people will not upgrade to the Pro because of its absurd pricing (note because it’s not worth it, but because the market for it is likely very niche).
I guess I will just skip Sony’s platform for this generation.
Just to say that the question might not only concern niche games. Any game that you do not buy shortly after its release might have a negative impact on the franchise (because most sales happen in a few weeks, with rare exceptions of course).
