Everyone Knows that the N64 sold below expectations in Japan(around 5 million units compared to the Saturn's 6 mil and the ps1's staggering 19 mil) so if we wanted Nintendo to become a multiplatform dev/publisher around the same time Sega did in otl, the N64 would probably have to sell even worse in Japan and it would have to sell less than the Saturn in America and Europe. For the handheld side however, I'll get to that later . As for what system Nintendo would develop for when they stop making consoles, for me, they definitely would not start developing stuff for Sony(aka the PS2) out of a grudge, they would consider making stuff for Dreamcast, but then comes in Microsoft with the Xbox, we all know that Microsoft tried to purchase Nintendo in otl and they got laughed at, but ITTL, with Nintendo financially strained, they still would not be bought out, but instead become sort of second party developer for the Xbox for a year or two. So stuff like Luigi's mansion and other launch titles for the GameCube by Nintendo, would be Xbox launch titles, with later titles like Metroid prime and the big boy, Mario sunshine, would be Xbox exclusives. Now for the handheld of Nintendo, for me, they would still make the GBA, with help from Microsoft, making the original Xbox and GBA brother and sister consoles like the GameCube and GBA was in otl. That's all that I can come up with. Could make for a cool timeline.
