Re: Black Crusade Vs Ascension.
A good, sound idea.
The major, foreseeable problem is character death. If you have them playing before they meet you'll eventually have them skirmish and someone will eventually come away dead or maimed, by which point the player will become very attached and protective of him/her. While we're all big boys and girls, that's a big time and effort investment would, for me, be annoying to have to start all over again.
