Some issues that might be addressed if we did Battlestar Galactica with Traveller rules.
First off the Raptors in the second series get replaces with the 100-ton Scout/Courier as it does the same job as the Raptor in the 2003 series. Also in the 2003 series the Jumps were instantaneous so raptors could be the size of helicopters, in the standard Traveller Game that's not going to fly as a Jump takes 5 days, the crew will need to live onboard the Scout/Courier while they wait to get out of Jump Space. Another problem is after scouting various star systems looking for Earth and avoiding the Cylons, somehow the Scout/Courier has to get back to the fleet, and there is no guarantee that they fleet will be at the last location. If the Cylons attacked it, the fleet is going to have to make a Jump in a hurry. It will probably remain outside the 100-diameter limit of any planet it is near, and it will have precalculated and distributed the Jump coordinates to all the ships in case the Cylons show up, the Scout ships will have to know what those prearranged jump coordinates are in advance before they undertake their mission. The Galactica could dispatch an X-boat to where the Scout ship was sent to inform them they had jumped to avoid the Cylons and telling them where they jumped so the Scout ship can meet up with them.
Another thing is that each of the ships will have to stock 5 days of food and supplies in case they have to Jump in a hurry. During those 5 days in jump space each ship will be alone and their will be no traveling between ships. There is about 30 Capital ships in the fleet, and more numerous smaller starships, such as the Mercenary Cruiser, Scout/Courier, Safari Ship, Lab Ship, Free Trader, Far Trader, Subsidized Liner, Patrol Cruisers. My guess is Colonial One would be a Subsidized Liner guarded by a couple Patrol Cruisers. The Battlestar Galactica is the only military Capital ship in the fleet, though the Battlestar Pegasus with Commaner Cane might show up at some time. What do you think the tonnage of the Battlestar Galactica should be? It is a huge ship with two landing decks and launch tubes for its fighters. The central portion of the ship is essentially a Battleship armed with missiles and a spinal mount, with possibly a black globe for defense. The Cylons have a more advanced Jump drive, in that they are not limited to 100-ton starships or greater, their Raiders have Jump drives, they are also automated and have no life support as the ships are Cylons themselves. The other type is the standard Centurian, these would be their troops, then their are the 12 model "skin jobs". The Basestars have a degree of self-awareness as well. Which do you like, the "double flying saucers" or the "jacks"? What should the centurians be armed with?
