Forza Horizon games aren't made by MS first party, and games like Bloodborne should be on the list based on rules specified.

Nintendo>>>>Sony>>>>>>>>>>>>>>>>>>>>>>>MS

I imagine Sony will overtake Nintendo pretty soon though. Still haven't played Uncharted 4 and Ratchet & Clank, and Last Guardian, Gravity Rush 2 and Horizon coming in the next 6 months (and hopefully GT Sport)

For me personally Playstation does hands down. And when you add in a ton of AA and AAA psvr titles it's going to be even more epic.

Take two makes horizon. Take two is owned by MS. Bloodborne was developed by form software but produced by Sony and published by Sony so that's why its not on the list.

Ill be honest because I tend to only like RPGs and games like Dark Souls, I am not impressed with any of the first party games. So I vote None. However, Sony seems to have the best exclusives based on the before mentioned preferences.

Forza Horizon is made by Playground Games, not owned by MS. I think Sony Japan helped with development too with Bloodborne, but maybe not

Its co developed with playground games.

Sony easily. Uncharted 4, inFamous: Second Son, Bloodborne (co developed by Japan Studios) + future first party games like Horizon, GoW4, TLOU2 do it for me.

Has The Last Of Us 2 been announced?

It has been hinted at, IIRC. 

End game credits will beg to differ. After Demon Souls Sony reached out to Miyazaki to rectify their mistake on being dismisive of ps3 exclusive Demon Souls, and wanted a sequel for Demon Souls, but miyazaki declined, as the concept had been altered to fit Dark Souls series. So Miyazaki proposed a new game at the end of Dark Souls 2 production for the next gen console but would require a new engine for sony exclusive and their future games, hence Sony Japan was brought in to speed up the development process and release the Bloodborne before Dark Souls 3.
