Nope. GURPS.
GT setting material had to adhere to previously published material unless TPTB specifically permitted retcons. Any GT detail about historical events is evidence for historical events in the OTU, and details set after the Change Point had to flow believably from earlier conditions.
Even Mongoose Traveller 3I has differences from CT. The CT Spinward Marches UWPs do not match the Mongoose ones, for example.
Those are known as retcons (Or mistakes
).
Then there are the version to version changes for nobility and Imperial law levels and related material.
Retcons. (What changes for nobility, BTW.? Plenty of additions in
GT:Nobles, but not many changes that I can recall. There's the viscount, which Marc Miller specifically requested (though he must have changed his mind again later, because he didn't insist on them for T20 and MGT
. Or perhaps he just forgot about them again.))
Add to that the differences in aliens - which are a part of the setting mixed into the post-CT rule sets.
Retcons. What changes, BTW?
Ship specs change from version to version as well. Most of these are minimal, but they are still version dependent differences related to the setting.
Technical specs are indeed version dependent. But the setting isn't. Characters with an Empress Marava in a CT adventure would still have an Empress Marava in any later adventures, regardless of the version. The ship the characters had in TTA they still have in BtC.
The thing is, you can take any of those setting changes introduced in later versions and use them with CT rules. Want to use all the information about nobles from
GT:Nobles in your CT campaign? What's to stop you? Want to visit the Bwap homeworld? Grab a copy of
GT:Alien Races 4 and use the information there. Sure, you'll have to convert any character you want to use from GT to CT, but without AR4 you would have to make them up from scratch.
