Damn, that trailer looks absolutely amazing. I love these sort of intros. My favorite gameplay environment is actually in nature so this is perfect, just like Far Cry 3 and 4 were.
There's also some fishing in the trailer, maybe we will finally have the option to cast out our rods and catch those fishes! Can't wait till it comes out, hope it doesn't disappoint.
Also, where did you see the character customization?? I don't see it in the trailer.
