Considered not doing this cause i don't want to start a war, but i feel it's necessary. PS4's second year from November 2014 through November 2015:
God of War III Remastered
Everybody's Gone to the Rapture
Beyond: Two Souls
How many games by the definition you have given to the Switch-games would you call big? So Bloodborne and nothing else.
Yep. Sony didn't really have much for 2015 either. But the difference is that Sony regularly gets brand new 3rd party games released on their system. So much so, that they don't need to practically single handily support their entire library, in the same way that Nintendo does.
I mean, look at all the new 3rd party AAA titles for PS4's 2015. There's a lot of them. http://www.gamerankings.com/browse.html?site=ps4&cat=0&year=2015&numrev=1&sort=0&letter=&search=
