Time for some Graphics!

I thought the graphics in Splinter Cell: Blacklist were very appealing, but a game with a more cartoon-y art style, I would have to say Dust: an Elysian Tail.

GTA V also has some quite impressive graphics compared to GTA IV.
And Borderlands 2 looks good too, even though people might disagree with the way it looks, still it looks pretty amazing.

These have all been mentioned already, but by far the best looking games I've played lately are The Last of Us and Beyond: Two Souls.

I play Skyrim vanilla, but I've seen some pretty impressive mods (that I can't run on my laptop).
