I have Force and Destiny, Age of Rebellion, and Edge of the Empire, which all appear to be compatible for running together on a surface level, they all use identical core mechanics and I was planning to GM them in a single setting, using the wealth of information from KoToR and SW:toR to set it post SW:toR and pre movie era.
The most obvious disparity is lightsabers, in EotE and AoR they have the same rules: damage 10 (same as a disruptor pistol and most heavy weapons) not counting breach, sunder, and vicious, however in F&D they start at damage 6 with the easiest crystals to obtain and range up to 9 with the most difficult crystal to obtain but disruptor pistols remain at damage 10.
The next issue is how to choose between or integrate destiny, duty, and obligations. Trying to bring them all together seems like it would create a broken system, destiny and obligations could be filled by a single thing such as the Jedi code and duty and obligations could be a single item as well, and I doubt it would take much imagination to fit all 3 into one item. Just to clarify by item I am not referring to a tangible object, it could be an internal struggle or ethic to a relationship with a person, organization, etc.
Is there anything published on the matter of combining the 3 FFG core Star Wars rules and resolving the disparities or has the community already tackled this question?
