Lol, some games were certainly buggy, but most games I played as a kid on my NES, SNES, Sega Genesis, N64, and Xbox worked pretty well. I remember by siblings being games testers as high school and college students, but that seems to no longer be a thing.
These days, only indie games seem to work okay day 1, and that’s not even a guarantee. Ever since WiFi became standard on consoles, it seems developers ship games way too early since they know they can patch it later.
