First, Hey great to see you.
Second, I hope this will be okay. I had a HUGE post typed up, the power blipped and I lost it all
#1. The CS RPG I have no clue, never tried playing it. It was designed with CLix in mind and...I am..somehow prejudiced..never even tried it.
#2. How is the Serenity RPG? I've heard of it, and thought of getting it and trying to convert it to CS.
#3. I am making one, however it is mostly involving fighting. Most of the RPG elements would be vocal interaction with players,etc. so it probably wouldn't translate to baordgame as easily.
As for pirates boarding zeppelins....ooohkay:
Generally all boarding actions are preceded by two things: Shooting down the fighter escort, and destroying the zeppelin's turrets.
#1. Official Canon FASA boarding gave us two options. Both involved loading boarders into a cargo bay, or clinging to wings (The latter always seemed ridiulous to me though).
Low freefall, in which the plane passed slow over the zeppelin and dropped boarders. They freefalled onto the zeppelin, then dug in grappling hooks into the zeppelin's cloth. They then rapelled down the side to the gondola, or to the engine nacelles and entered through the gunner's hatches.
Walkoff. In which the plane stalls right overtop the zeppelin, and allows the boarders to simply walk off the cargo bay and onto the zeppelins top, again, usually rapelling down the side. The downside to this is if the cargo plane fails a stall roll (Die roll) it will crash into the zeppelin.
#2. Yahzuk gave us two alternatives: The Zipline, in which the aircraft fires a rocket with attached zipline into the zeppelin, and deposits it's boarders that way.
OR the boarding aircraft can dock onto a hook and deposit it's boarders directly into the launch bay. I personally don't care for it, as I don't see an enemy plane being allowed to dock onto a zeppelin (Much less pulled inside), and even if it did, it's boarders would be VERY vulnerable to fire, which in my opinion, 4 greasemonkeys with Thompsons could take most out.
#3. As I don't have official rules, I have zeppelins also capable of boarding enemy zeppelins. If enough engines (And rudders, to prevent hard turning and snapping the cables) are destroyed, docking lines are fired between the attacking and crippled zeppelin, with ziplines carrying boarders running between them, and possibly, if enough under friendly control, temporary suspension bridges.
On all landing types, various difficulties (Die rolls) are required for success.
However whenever a zeppelin is attacked (Usually) for valuables, they are intended to be boarded. Crashing would destroy most valuables. SOMETIMES, however a pirate gang could accidentally destroy a zeppelin (Igniting hydrogen cells for example), OR be paid to destroy a zeppelin.
None of this si covered by the "official" RPG, which is really just a combat game.
Hope that helps!
P.S. Fencing goods. Might be done in a nation who is enemy to the captured zeppelin, but most likely only in pirate refuges, such as Appalachia, Colorado,etc.etc.
