Game prices for the past 30 years haven’t kept pace with inflation.
I recognise the argument that publishers are shifting larger volumes of units now, which has been a factor that has allowed the industry to keep price increases below inflation for the last 30 years.
Wages not being even close to keeping up with inflation (especially housing inflation) is the real issue here, not the $70/$80 video game.
You should be angry at your reduced purchasing power in all of society, not just with the price of Nintendo games.
(Secondary less unpopular opinion, the best games out these days are multiplatform and released at least 5 years ago, buy them for << $80 and wait for sale the new releases, when they too are 5 years old)
What has gotten much more expensive is the 3D modelling and level/gamespace making side of things, rather than development, which is why you see so many indies doing 2D games or simple 3D visuals and procedural generation of the gamespace.
This is partly why indie studios are far more successful at producing games with great gameplay than AAA studios - since they avoid going for hyper-realistic looks and massive hand-crafted levels they can focus on the actual gaming much more, plus its way easier to pivot main aspects of a game if it turns out they’re not actually fun if there isn’t a massive amount of time sunk into visuals and level design linked to them.
