From a technological stand point I'd say either Uncharted 3 or The Last of Us, but aesthetically my personal favourite is Valkyria Chronicles. The visual style in that game is just impeccable.

I gotta go with Uncharted 3. 

The scope and complexity of the setpieces it handles while still maintaining a superb level of effects and asset quality and a mostly stable framerate is really remarkable. From the lighting to the animation to the textures it all just comes together so cohesively and consistently, and the attention to detail is just astounding.

I'll go with Final Fantasy XIII.

With God of War, Uncharted 3 and the likes already mentioned, below games are quite the lookers as well.

Gran Turismo 6:


AC IV: Black Flag


Destiny:


Alien Isolation:

Like everyone I was most impressed with The Last of Us, but the final word belonged to AC4 Black Flag, that game is insane for PS3.

On PS3, best graphic:

Uncharted 2/3, The Last of Us, Persona 5 and Ni No Kuni :)

Well we do know that Gran Turismo would have the top spot, but since racing simulator have to many privileges to make it easier to make outstanding graphics I'll go with TLOU.

There were plenty of other great games as listed, Beyond 2 Souls, God of War and Killzone to try and take out TLOU. But not only TLOU was ND it was also the last big hitter beside GT (and they had other 3 games developed on the system) so ND probably were the devs who could use PS3 the best for graphics.

Man those are all fantastic graphic games but my choice would be TLoU. But hands down KZ3 was the best looking (non-PC) FPS last gen (IMO ofc).

Please explain to us how GTA5 have a better graphic than TLOU on PS3.

uncharted 3 by far
