"3rd party support"
Y'all just say stuff
Let's act like the Super Nintendo over Sega Genesis wasn't a thing.
The thing that wins every generations console "war" is 3rd party support 1st then graphics.
It's why NES dominated
It's why SNES won
It's why PS1 won
It's why the PS2 won
It's why the 360 almost won.
It's why the PS4 won
Sony Stan's did their best to try and change the narrative towards the end of the PS4 generation with 1st party "console exclusives" only to walk that back with the PS5 and it having to lean on "3rd party exclusives" and sharing their "console exclusives" on PC now.
Nah, games wins every generation, period. Be it first or 3rd party, games win.
I can run down a list of consoles with better "graphics" that ended up in last place.
Lastly I'm noticing you left out the Nintendo Wii.
