When I was growing up in Nigeria - and I shouldn't say Nigeria, because that's too general, but in Afikpo, the Igbo part of the country where I'm from - there were always rites of passage for young men. Men were taught to be men in the ways in which we are not women; that's essentially what it is.

'Star Wars,' 'Doctor Who,' 'Forgotten Realms,' even 'Firefly' and 'The X-Files' have shared world novels and other media. I can't help but notice these settings have large shelf space in bookstores, so their publishers and authors are getting something right.
