LMfao the denial

nintendo + third party maybe we just have to buy only a console not two

The one thing we would've seen is a lot of multiplatform games. Nintendo's relationship with most 3rd parties was in the dumps but they certainly would've released most games on both PSX and N64 at the same time. The N64 sold really well in the US, so western support would've been decent. Lots of games couldn't fit on a cartridge because of CGI. Well, they probably could by compressing the files but that would still require a 512Mbit cartridge - which was hellishly costly back in the day (a $10 premium at retail I think).

Cartridges were held back by more than just their small space though: Producing them was extremely costly and Nintendo built the cartridges. Because of that third parties had to accurately predict their game shipments beforehand - that often resulted in shortages (money lost) or overshipping (lots and lots of money lost due to each cartridge being like $5 to produce - compared to ¢5 or so for a CD). There were also stories of Nintendo cutting cartridge shipments to third parties whenever they ran into a shortage for their own games. Also, producing a second shipment took weeks or even a month.

Sadly, well for us Nintendo fans, that part is true.

The N64 was delayed beyond belief, allowing Sony to release the PS1 over a year before the N64. Being first helped Sony greatly. Also, publishers were already looking for a way out of Nintendo's tight grip, so they happily supported the newcomer in favor of Nintendo. Victory was Sony's already. When N64 took on the cartridge format too, that was just icing on the cake.

But anyway, I still think the N64 is the best thing to have happened to gaming so I don't care .

In retrospect cartridges have been a very big mistake. While loading times were great for cartridges they were far too costly, which resulted to multiple times more production costs compared to cheap CDs and more storage capacity. CDs had therefore the benefit to be more profitable and also less risky which was especially appealing to small publishers. Also it allowed to publish magazines with game demoes which really helped the marketing for those games. The benefits for cartridges have been superior loading times, a medium that isn´t as vulnerable you can save your gamedata on the cartridge and also had a higher longevity, while these are legit advantages it just wasnt economically competetive.

The Playstation was still taking its baby steps in 1996, adoption of the PSX and Saturn early on in their life cycles was extremely slow.

The N64 sold far quicker out of the gate, but couldn't sustain the torrid pace. Actually the N64 sold faster out of the gate than any of the modern game consoles, even having a faster sell through than the Wii (it wasn't as supply restricted) in North America. It sold past 2 million in North America without any problem. 

I get the feeling a lot of people here weren't even gaming or just little kids in the mid-90s, lol and are applying revisionist history.

It wasn't really until mid-1997 that I think a lot of people realized exactly what choosing cartridges over CDs meant for Nintendo and that the N64 wasn't going to have the same level of support as the NES and SNES. Most people expected that, they didn't know, up until then the idea of a Nintendo console without third party games was pretty alien.

Why do some people think the PSX was dominating before the release of the N64?

The 16-bit consoles heavily dominated until the release of the N64, and it was a some time later that the PSX picked up steam, in around the time of the release of Final Fantasy 7, Tomb Raider 2, Resident Evil Director's Cut, and the hype for Resident Evil 2.

Before then, the PSX wasn't even as big as the Sega Saturn.

^^

Saturn was quite popular in Japan yes, but the PlayStation had absolutely no problem in the US and Europe in overtaking the Saturn's lifetime sales very early into the gen.

The Saturn stumbled out of the gate due to SEGA's incompetence. PS1 had already solidified it's place enough when the N64 released in all regions. It wasn't like the N64 didn't have a chance at all though, I agree, but it couldn't really compete with the number of games being released on the PS1. N64 sold exremely well during launch window solely because of Mario 64, it really is one of the most revolutionary games ever made.

However, because 30m of the PS1's sales came from the redesign during the course of the 6th gen, the end result was indeed a lot closer too than what it may seem today (35 vs. 70 instead of 35 vs. 100).

Wave Race 64 was amazing too and Killer Instinct Gold and Pilotwings 64 were underrated titles IMO. Fun to play. Even Shadows of the Empire for that time, considering 3D games were in their infancy was an OK game.

The N64 also got Mario Kart 64 very quickly too. In its first five-six months it had

Super Mario 64
Wave Race 64
Pilotwings 64
Mario Kart 64
Killer Instinct Gold
Blast Corps
Turok: Dinosaur Hunter
Gretzky 3D Hockey

Because of the lack of CD-ROM there just weren't multiplats, but if it had a CD drive as well, it probably also would've gotten a Resident Evil port and several other games in the launch window.

But that launch window -- destroys the Wii, Wii U, GameCube, PS2, PS1, PS3, etc. if you ask me just on exclusives.

CDs put the final nail in the coffin of chiptunes. FUCK YOU XA.
