yeah this is what i always use as reference, JC, great map HUGE map but empty as hell.

once the map comes out we can actually see how they utilized the space, i do wish we had more info but i'm fairly confident it has more playable area then skyrim or fallout 3

I think the reason for the JC2 Huge map was so you could just have a sandbox to play in. It wasnt meant to be anything more. That said, a JC2 type map for FO4 would make me sad.
