I always thought of Nerf as a running-around-in-the-garden kind of thing.
Today, I met some people with some properly cool Nerf gear, aimed at adults / more serious players. High pressure air blasters, magazine-fed semi and full automatic blasters and the like.
I'd rather like to give it a go some point!
@neil does this not lead to Collecting Millions Of Nerf Darts at the close of play though?
