PS1 was kind of a slow starter compared to todays consoles. N64 shipped more in it's first 2 years than PS1 did... just that by the time N64 launched PS1 was just hitting it's stride.
Earlier release (or more specifically late release of N64... PS1's competion was the Saturn & the aging SNES)
Discs (allowed for better sound & more space but also allowed them to sell the games using the video cutscenes)
Discs again, as they were cheaper for 3rd parties = more incentive for publishers to make games for it.
Nintendo's prior treatment of 3rd parties no doubt also played a factor
Sony's already existing huge worldwide brand power, Nintendo only really had a strong Japanese & US presence. This also extends to availability, I think back then apart from Japan, USA, & the big 5 in EU Nintendo didn't directly sell in any other countries... I think they had a partnership with a company to cover Scandanavia, and maybe Canada came under NoA umbrella... the rest of Europe & rest of the world would only be able to get grey imports.Last edited by HigHurtenflurst - on 18 November 2020
