As far as graphics?
Alien Isolation (PS4) So real!
Battlefield 4 (PS4)
TLOU (PS4) - Incredible art direction
Infamous Second Son (PS4)
Watch Dogs (PS4) - Can look photo reaistic at times its scary
And the big one
AC Unity (PS4) - Though I found the gameplay average and boring after a bit, the graphics, texture detail, lighting, art direction and overall detail in this game is absolutely mind blowing insane. It litterally looks like real life at times. No wonder the game runs @ the framerate it does on PS4, those tiny CPUs are getting overloaded.
Gameplay wise - 'blown away' standards
TLOU - really needs no expanation - Masterpiece
Alien isolation - amazing atmosphere and they nailed the Alien environment,tension. Incredible experience.
There are 'great' games out there but those 2 fit the 'blown away' category
I have yet to play Far Cry 4 or Dragon Inquisition yet.
