Got a PS4 Slim as a gift, and started Horizon Zero Dawn last night when I got home from being out of town.
Holy Crap. This game is incredible. Still only in the first area, but I'm in awe over the vivid colors, the sprawling landscape, and... Robots. Serious props to the AI team!
Already this is turning out to be one of my favorite games I've played.
Loved it. Just wait until you start discovering clues about the story / why the world is the way it is, there's some seriously interesting plot twists.
