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.

My grand uncle was a traditional priest, and he would always say to me as a kid, 'We stand in our own light,' which essentially for him meant we were entirely responsible for a lot of what happens to us and for the ways in which our lives play out.

'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.
