Exactly what it says on the tin really....how much would the starting Deathwatch talents, and access to the advancement tables be worth (the skills you can pretty much work out) in xp?
I ask as I'm thinking of including a non-Deathwatch Space Marine PC in our game (which is a mixed Deathwatch/Ascended Dark Heresy thing) and was going to try to retcon him from the DW creation rules.
