I recently bought a PS3 in order to play the exclusives. I mainly play on Pc so thats something I do, I buy all the best stuff when everything has dropped in price. I have all the PS3 exclusives to look forward to.
Before we get any further, may I recommend Journey? You should be able to pick it up cheap and it's really a great game. Actually it's one of the best games I've never played - I sat my girlfriend down and gave her the controller and she loved it. I just sat there watching her play and helping her through some bits (she's not much of a gamer, but she plays some stuff like Mario, Mortal Kombat and such [wow, what the hell would "and such" mean there actually?!]). Red Dead Redemption is also worth getting, though as a PC gamer you'll probably be wishing you had a mouse instead of auto-aim x.x
Try some fighters also if you're into them, they can be great fun, especially with mates. I recommend MK9 if you have a bunch of friends and want to play with them (2vs2 ladder with a friend or just fight 1vs1 or 2vs2 with friends) and Injustice: Gods Among Us if you want to play online (though be warned, game's come out a while ago and there aren't too many players still playing it; you can get regular fights, just... keep it in mind).

I tried Uncharted and kill zone but I quit after 30 minutes.
I haven't played The Last of Us (I'll get it when it gets cheaper, disposable income isn't really my thing and the price has been going strong for ages due to the positive reception) or Killzone, but Uncharted didn't leave me stunned either. Have you played the previous games? I only played the third one (was free on PS+) and while it was enjoyable, it wasn't something I'd actually recommend to anyone new to the series. I did have the feeling that people who've played the other games might've enjoyed it more than I did though.
Just some thoughts/recommendations. But if you're not feeling gaming anymore... well, bit sad for you, but hey, plenty of other things to do in life. That said, you might want to make sure you're not just burned out on mediocre games and get some things that would be more up your alley and less "everyone says it's amazing so I must enjoy it". That goes for my own suggestions above too
Another thought, have you played/liked Dark Souls on PC? You have the Demon's Souls on PS3 and it's quite good. If you haven't tried either, you might want to give it a go, though be warned, you might need to look up a few guides at the beginning if you're having trouble figuring it out (no shame in it, I did, felt like dropping the game, then figured it'd be better to spoil it a bit for myself in hopes of liking it than just giving up on it and it ended up being immensely enjoyable, one of my favourite games)
