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)
One thing that was different in the 90s was that even though games were expensive to buy outright rental shops were common. I played loads of N64, SNES and Mega Drive games for paying £2.99 for the weekend. Plus games were more stand alone as well so you got more for your money.
