What's with all the nerd hate? If this is what he wants to do and he can find people to do it with him, more power to him. No need to tear him down because you don't like it.
It's not what I want to do either, and it certainly wouldn't work for an open-to-all-comers scenario, but for a group of friends that want to get out and play I see nothing wrong with it.
And I'm also a big nerd. Hell, most of the people I know that play are big nerds in one way or another.
