Base Jumping In Just Cause 2

Check out the latest developer diary for Just Cause 2 and be amazed by the things you can do with a grappling hook and a parachute. Imagine Spiderman para-sailing. It seems that the trend lately with video games has been to bring more of the game terrain/area to the player, and make the world as a whole more accessible. Long have we veered away from the typical side-scroller, only to have a full vertical as well as horizontal feel to our video game worlds. No longer is the player bound by the rules of up, down, left, and right.

I don't know about the rest of the community, but as soon as i get this game i'm finding the highest building humanly possible and jumping. I wonder if there's an achievement for that?
