The success of the PS1 didn’t help either. Sony had already stolen Sega’s market (and some of Nintendo’s too where people were annoyed with the cartridge decision).

Ironically the N64 was a more interesting console than the PS1 and the Dreamcast was more interesting than the PS2; but most people didn’t care. Sony really understood what the lion share of gamers wanted - or perhaps it was just good fortune to step into the market when the other giants misstepped?

Ironically Sony tried to work with both Sega and Nintendo and got rejected by both after investing substantial time on a collaboration. It’s funny how quickly the market turned.
