$100 today is about $40 in 1990. In those days games were made by a handful of people or even a single individual in one of two years of development. Chris Sawyer started work on the 1994 classic Transport Tycoon in 1992 and wrote the entire codebase in x86 Assembly. The price isn’t really that crazy considering the comparatively massive undertaking that is GTA6 development.

Having said that, it’s rare nowadays for any AAA game to release anywhere near its best state, so it tends to be worth it to wait even if money isn’t the concern.
