Nintendo didnt make Xenoblade or the Last Story.

Sony also hasnt made Uncharted, God of war, GT...

Nintendo can get away with saying things like this because they've survived generations without majorly large third party support. They are right though, Microsoft's first party is so weak they get into bidding wars over exclusives. That would tarnish what Microsoft has been all about. It's more an act of discipline than anything, but their selection will tell the story against the competition so we'll see.

Yes they did. Those are all first party.

Erm... Xenoblade was made by Monolith Soft, which is owned by Nintendo.

Nintendo weren't the developers of The Last Story, not actually owning Mistwalker, but it was made in collaboration with Nintendo, and financed by Nintendo, and thus is still counted, as much as Pokemon (made by GameFreak, a second-party developer for Nintendo) is still a Nintendo series.

Uncharted Naughty dog
GT Polyphony digital

if those are made by Sony then Xenoblade should count also as a Nintendo game....

GoW is a SOny game indeed..my bad sorry

Interesting Namco must've sold the shares to Nintendo. Theres never been a Xenoblade game exclusive to Nintendo or even on it, its usually Playstation. This explains why there was no Xenoblade on the PS3 this gen. 

All Sony companies.

I thought this was old news....

going against MS would be insane and pointless as MS will pay crazy amount of cash to secure exclusive games! Nintendo should use that money on their own projects

The same as Monolith and Retro and Hal lab. and
its called second partys
