I mean tbf complaining that less people can afford it now because prices have increased but wages haven’t is fair. Everything needs to be looked at relative to all the other values. If you wanna go even more in depth I guess you would need to add popularity of games, reputation of a brand or game series, value of the currency, and other factors.

I generally agree with you that prices for video games haven’t kept up that well, although I would also point out that due to multiple factors anchoring the video game price at 1980 might not be the best if you want a fitting picture. Games were much more rare baack then, the market was smaller, small production volume meant physical costs per unit increase, there’s things like way higher shipping costs to think about because globalization is a more modern phenomenon and a lot more stuff. Imo using the 2000s as an anchor to extrapolate from would be more fitting, as the market was well established at that point and thus prices would appear more stable.

I’m not doing that because I am literally a little gremlin who can’t be arsed to put the time in rn but these are my two cents of criticism against your methodology.
