#backinmyday, video games were released ‘finished’: if there were any bugs found in them post release, they’d be in the game forevermore.
This was a mixed bag in many ways. If a game was broken or glitchy to a ridiculous extent (ET on Atari, Superman 64, etc) it was stuck like that, so that wasn’t ideal…
But it also meant many games couldn’t be released unfinished and fixed with updates either, and the devs couldn’t patch out any glitches or finds the players liked.
