Well, it seems the campaign performance get's better once you get out of the starting area. And oh my, is it a blast or what?
The world really feels like it's alive, just came upon a few cows in the middle of nowhere. Also, it's great how there's enemy patrols all around so you just cant run around with time compression at max (I say run around, because my Huey pilot though it would be a fun gag to crash the darn chopper
).
