Trying to predict how NV will be based on the trailer is like trying to predict Global Warming - everyone is an expert, and yet no one really knows worth a damn what will happen. But it sure is fun to watch all the banter back and forth, declarations of its qualities, statements of developer intent - isn't imagination just Wonderful?

From what we learned from the trailer, I believe FNV will be Puff The Magic Dragon: The Game.

I for one believe that the mountains surrounding New Vegas in this game mean it will be heavily focused on mountain climbing.

Ok, yours was better.

When i saw the city i was so happy can't wait to explore Sin City

There was no climb feature in Fallout 3 and since that's a pretty advanced thing to implement in a game (any game!), I'm more thinking they're using the mountains as natural barriers for the player.. instead of those ridiculous invisible walls Bethesda used.

Oopsie - time for a new one!
