Re: 'Becoming a Game Writer'
I guess the best way to become a game writer remains to have a games related blog or to join such kind of blog and write, write and write again... You need to show of course that you have skills but also that you will still write in a not so close future... A lot of people start writing and think they enjoy it but stop writing quickly.
Son my advice would be to write on your own for at least a few months before trying to get in touch with popular websites.
Have fun ! ;-)
