Good review as usual from Alex, but he made an error in there....
" No, they don’t just drop in out of thin air. It’s more like you’ll turn a corner, and suddenly they’ll be standing there. Or you’ll jump off a ledge, and they’ll be waiting for you at the bottom. It’s a completely seamless transition."
That is just completely untrue. I'm thinking there's a tree falling in the woods thing going on here, because if you are there to see it, they in fact LITERALLY "drop in out of thin air"; I just saw it last night myself.
I was walking over a dune, and a dude quite literally popped into existance standing next to me. I'm not suggesting it was chaotic or wierd or anything, but this idea that they are just "there" is not true, it's a perception.
Regardless though, outstdnaing game; one of the best I've ever played frankly.
