Completely agree, for every case where the increased price may makes sense, there are dozens (if not hundreds) where it makes no sense at all (other than increasing the profit of shareholders, which makes complete sense).

Depend on the game. There are still many single players games that don’t have any MTX etc, Sony first party games are like that, and so are most Nintendo games. Sony often release a DLC, which cost more, but that’s more money for more content, and you don’t need DLC.
