All the Assassins games have been dissapointing so far, Destiny was a dissapointment, Andromeda was a disspointment, The Division and Watch Dogs weren't what they were supposed to be.  Battlefield 4 was buggy as hell, Battlefront lacked content. The PS4 best games so far have been RPGs - Bloodbourne, The Witcher 3, Dragon Age, Horizon, etc.  The only two games that really delivered and were not RPG or Sports games were Uncharted 4 and Battlefield 1. And they came in the last 12 months. What were people not playing sports games or RPG playing in the 3 years prior. At least games like Battlefront 2, AC Origins, Spiderman, Detroit Became Human, God of War, Spiderman, Anthem, Red Redemption are coming in the next 18 months.

Farcry 4, Doom, Wolfestien, battlefield 4 and Infamous pop on to the top of my head.

No

my recommendations are:

watch dogs 2

Rise of the Tomb Raider

Ratchet and clank

gravity rush 2

Mad Max

Assassin's Creed syndicate (the best AC after AC 2)

Noo.

Sony is known for action adventure games and third person shooters these days. They have all of the multiplats as well. 

Have no issues finding a game to play to fit my taste.

all the games you cite are multiplateforme

In terms of exclusive shooters its lacking.
