I am a fan of RT but having had some time to look over the rules for DH2, I found that I prefer the advancement system there.
In fact, I am thinking of using the rules from DH2 and just adding the 'missing' parts from RT, (like Ship rules, etc).
While some parts are easy to model (most Careers become Backgrounds easily enough), there is some things that are a little trickier. Likewise some of the roles played in RT are not among the Roles (capital R for rules/OOC) in DH2.
So I am going to use this space to brainstorm, get feedback and develop a set of Stopgap rules until RT2 comes out...Assuming FFG doesn't shoot itself in the foot.
