7. Wii U - It really failed to attract third parties, it lived only on Nintendo's own released. It wasn't all bad though, the first year it got some of the big titles. And unlike previous Nintendo consoles, it had the benefit of indie support.
6. Wii - Considering the success of this one, the third party support is really embarrasing. It either didn't get the cross platform games, or it got weak versions. It's exclusive third party titles were often shovelware. However there were a handful of really good 3. party titles, such as Red Steel 2, Rayman Origins, GoldenEye 007, World of Goo etc.
5. Gamecube - It actually got a fair amount of the cross-platform titles, however, considering how capable it was, it is pretty weak that it often got overlooked by third parties, and the titles it got barely looked better than the PS2 versions and considerably worse than the Xbox versions. It also barely got any noteworthy third party exclusives.
4. Nintendo 64 - It didn't get the quantity, but it got the quality. It's third party cross-platform titles were often the definitive versions. It also got a lot of third party exclusives, such as Doom 64, Turok titles, WWF: No Mercy, StarCraft 64,
007: The World Is Not Enough, Rogue:Squadron.
3. Switch - It might lack behind some of the others in quantity and exclusives. But the fact that you can take these AAA games with you on the go, is just impressive. Unlike the Wii, the ports for Switch are good quality. It also has better indie support than pretty much any system, another huge plus.
2. SNES - Well it was the king of the market for a reason. It crushed the competition when it came to third party support. I cannot put it first though, because most of the big third party exclusives were RPGs, while number 1 had it all for itself.
1. Nes - So many third party franchises came to existance here: Castlevania, Mega Man, Metal Gear, Contra, Ninja Gaiden, Final Fantasy. It had everything.
