I think I saw that some of the old arcade games were actually rigged to get harder at certain points to get more quarters/tokens put in them, then there was the countdown timer after you died where you could continue if you put more money in.

Video games are for-profit companies and these days they are in heavy competition with each other and all the other distractions around.

I can easily spend about $40-50 to go to a movie with the family and if the movie sucks it feels like a waste of 2 hours. Same amount of money on a game will get you 10x plus more time of entertainment.
