Solo Adventures?

Anyone ever run a solo campaign?<br />Having only two PCs might be almost as good as a solo campaign.<br /><br />I was writing an article on alternative beginnings to the Volturnus Campaign and one of them involved a Star Law marshal as a solo campaign investigating the selling of ships that have been reported lost and had insurance premiums paid out. <br /><br />It occured to me that since a Star Law characters start fairly advanced (Details in Dragano #91 also see details heres: http://frontierexplorer.org/book/creating-your-character ) that such a character could possibly survive a solo run of the Volturnus campaign.<br /><br />So I suppose that when it comes to the question of a solo campaign its also a question of how advanced a character is. I'm thinking that a solo character would need to be comparable to a Star Law Marshal.
