Literally nothing ever has stayed in lockstep with wages, that’s not even relevant to the discussion at hand. Not sure why you think video games would be special, especially video games by Nintendo, solijce they’re literally the last ones on the “raise video game prices” train.
Uh, video games have VERY famously not been decreasing in cost to create- AAA games cost VASTLY more to create now than in 2008. The teams are much, much larger, for one.
It’s a trend I personally think is stupid and unnecessary, but productivity gains aren’t really happening that way in game dev.
