I JUST saw this game in action today, and I agree. It IS fun to blow shit up.
...Oh, and the story [There's a story?] isn't important because of all the nice things to blow up.
And the map. Oh. My. Gordon Freeman. That thing is bigger than the budget on a James Cameron movie. There's a desert, a mountain range, about twelve seas, some cities, a hell of a lot of trees, sky everywhere for you to surf planes around in, more trees, cars, and even an oil rig or two. And some trees.
Also hovervehicles. Those are cool.
[And if the CIA is really this cool, why aren't there more pictures of it?]
