Well, the only game I've played on it since getting it last August is The Last of Us: Remastered
If my PS3 hadn't been on its last legs, I probably wouldn't have bothered at that time just for TLOU:R.
I also have Infamous Second Son, Resogun, and Super Stardust, along with some PS+ stuff. Not touched them yet, but then again, I have a much bigger Pile of Shame for my Xbox One.
*If* there are enough exclusives that interest you, then I think it's worth it. Otherwise, best wait... for Uncharted 4.
