You're looking at things in hindsight.Nah, dog. The base prices of those games back then are still a hundred bucks today EASY.
50 bucks early 90s is a yard today fam. 100 bucks. And these were games with limited games and substantially lower budgets.
Games were more expensive back then but the industry overall was far less profitable than it is now. It wasn't like most of those developers were swimming in cash.
