For me personally, it was Uncharted 2 back in 2009.

How about you?

The Order even so the game was meh and I paid only $9.

But it is the most bealtiful graphics I saw in a videogame including PC until now.

I honestly don't think I've ever been blown away by a game's graphics.

I actually get blown away pretty frequently by a lot of older games, it's pretty amazing to see how good some games' graphics were for their time.

Driveclub the thread.

Ninja Gaiden on the original Xbox. That thing looked better than a lot of Xbox 360 games.

Hmm, probably Infamous 2nd Son and The Order: 1886? Those had some stunning graphics O:

Pokémon X/Y.

Dragon Quest VIII. It's not because they were the 'best' or most realistic, but because they were... idk, what I had always been looking for in a game I suppose :P

Infamous Second Son I think for me. Driveclub blows my mind but in recent history Infamous is probably higher.
