There's definitely a narrative that the PS4 doesn't have any good exclusives.
I kind of agreed until Driveclub, but a lot of people seem down on that one, too. I didn't buy it until a couple of weeks ago, though, so I missed the launch troubles.
Still, though. Killzone and Knack were pretty bad to mediocre. InFamous was a beautiful game, but I found it to be extremely boring. I don't know anyone who played the PS4 Little Big Planet and I've no interest in it, either. Combine that with Sony's other first party output in recent years--stuff like Puppeteer, Tearaway, God of War: Ascension, Beyond: Two Souls--and you've got a bit of a pattern of beautiful but boring-as-hell games. I think it's understandable that a lot of people are a bit skeptical when it's not Gran Turismo or a game with Naughty Dog at the helm.
