Just be thankful they haven't followed inflation of both the value of money, and their budgets. A $40 NES game would be $120 in todays money and it was probably made in a month by three people in a shed, meanwhile something like CoD Black Ops Cold War credits over 9000 people and had a budget of $700 million. GTA 6 has already blown past a billion.
In fact, video games are currently pretty much the cheapest they've ever been, comparatively speaking.
Yep, that's why the best selling games consoles with the largest user base for selling all those super expensive AAA games are all the modern ones, like the Playstation 2, Nintendo DS, the Switch and the Gameboy Colour.
