So, as someone playing for the first time, I have to say, this game fully justifies all the hype it has.
I've never seen such emotional voice acting (specially in the prologue when
- this actually brought tears to my eyes). Framerate (60 FPS) is super tight and I haven't noticed any drops even with loads of NPCs on screen.
Graphics are very nice, specially when you take into account that this is a last gen game (but despite being perhaps the best looking console game of last gen, it kinda goes to show that there is a big gap between best of PS3 and earliest of PS4 (Killzone, Infamous), despite what some people claim, that there isn't a large enough gap between generations).
Gameplay in general is amazing, it's truly about survival. I love how the ammo is very scarce and you have to be careful with every shot, crafting system is great. Character animations are excellent.
Oh and by the way, once you go 60 FPS, there is no going back. I tried locking to 30 FPS and the moment I started turning around the camera, I almost screamed: GOD, NO!!!! Reverted to 60 FPS in about 5 seconds, never touched that unholy option again. I have no problem playing 30 FPS games, but given the choice, 60 FPS all the way.
