Okay, I consulted wikipedia and here's a list of exclusive games that could be worth it;
KNACK
Nathan Drake Collection
Uncharted 4 (Coming soon)
Infamous: Second Son
The Last Guardian (Coming Soon™)
Nier: Automata (Coming Soon >__>)
Ratchet and Clank
Until Dawn
The rest of the exclusives didn't seem very interesting or ist stuff nobody's outside of Japan, except for weebs, heard about.
