On paper, sure.
But as you point out, the world looks barren, there's not much there in terms of gameplay, and the performance leaves a lot to be desired. What I watched doesn't look fun to play, so it's hard to get excited.
I don't mean to rain on anyone's parade, as I know fans have been clamoring for this open world concept for a long time. But an open world alone doesn't mean a great game.
