@Edent It really is wild how inflation has crept up on us and "expensive" games today are actually cheaper than they were decades ago.
One other thing that contributes to game prices staying stable or dropping in absolute terms is that game manufacturers capture a larger percentage of the retail price these days. Games sold physically have to account for the retailer and distributor's profits so in the past they'd get maybe 50% of the retail price while with digital downloads it's more like 70% to 100% depending on the storefront.
