I disagree. The cartridge system with fast loading time and 4-player multiplayer are just remnants of their previous console, the SNES had these things. The major thing for the N64 was indeed the 3D. And that it was designed around. But it wasn't idiosyncratic. In practice the N64 introduced or popularized concepts that are now commonplace in 3D games, like the analogue stick for control in 3D environments or the lock on feature (Zelda OoT). This was very influential, which shows that it wasn't peculiar or idiosyncratic. N64 just wasn't successful, but it was very influental.

Yeah bit carts were super expensive compared to CDs which is why third party left Nintendo.

That's my point. What Nintendo was designing for their system didn't always align with what third parties wanted. Several of Nintendo's consoles like the N64, GCN, and Wii were designed with a very specific vision with Nintendo hoping third parties will embrace it as well, with mixed results. Whereas when Nintendo designs something a bit more standardized such as the DS, 3DS, GBA or Switch, developers are more eager to support it.

I fully agree.  Nintendo doesn't cater, historically, to third party like Sony did.  Their consoles were very much focused on first party games.

Obviously, Nintendo consoles are very much driven by first part games. But I never really bought the line that "Nintendo actively hates third parties because grr!!!", they may have had a pretty hostile attitude towards them in the Yamauchi days, but definitely not in the Iwata and beyond years. With GameCube, Wii, and Wii U, we did see genuine efforts by Nintendo to attract other developers to their home consoles. Even if it didn't always pan out the way they wanted, you can't say they didn't try to make their stuff look appealing.

I don't think  anyone said they hate thirdpartys but it differently not very important to them. I think we can say the same even about Switch 2 with out long it's taking to come out it's gonna be very dated for many of the bigger thirdparty  games 

They do think it's important. They wouldn't have gone out of their way to make sure the Switch was as compatible with modern game dev tools as possible if that wasn't the case.

I think what you and I think is important are 2 totally different things. The Switch hardware was just based on what was available for a amazing price of course they are gonna make the best out of it for thirdpartys. Looking at how long Switch 2 is taking and the hardware specs it's gonna be really dated when it comes out unless they surprise us which I doubt. They litterly just gave ps5 almost 5 Years of thirdparty games with out real competition, if it was priority we would see. Switch 2 end of 2023 

I mean yeah, it needed to be like that because its a mobile device, so it needs to consider things like battery life, heat consumption, physical size etc. And getting the most out of whatever is currently available has always been Nintendo's thing with hardware. NES, Game Boy, SNES, GBA, NDS, Wii, 3DS, Switch were all built with this approach, and its worked more often than it hasn't.

And like I said, people really overestimate just how much most developers actually care about having super powerful specs. Most developers just want an easy-to-develop for system with a lot of flexibility and a good development environment.

Most thirdpartys want a powerful system with a good development environment.  Well I guess it depends what  developers you are talking about but most AAA games do like to push the consoles to their limits. we already see engines like u5 struggles with current gen consoles.
