You seem to miss the point it was almost 30 years ago and they spend 18 months developing with a team of 20 people. Read those numbers again. Damn, the electrical bills alone to create Starfield most probably surpasses the entire development cost of a handful of SNES games combined. Yes, old games had manuals and came in physical form but those components where cheap at the time.
I’m not saying game SHOULD cost more. I’m just claiming games haven’t become a lot more expensive.
