Two main changes in mine so far:
Boughene/Regina (SM1904) (Wiki) became
Brainstorming Boughene (CotI Thread).
Biggest change is that due to a glitch (my mistake) in looking it up (generating it) on TravellerWorlds, I shoved it into a hole. IMTU it's orbiting the gas giant Komesh in Orbit 0 of the red-dwarf (M1 V) primary, so it's inside not only Komesh's 100D limit, but also that of the star. In the OTU, Boughene may be close in, but it's not
also in the gas giant's gravity well.
Canon sources understate just how freakin'
big Boughene Station is. 600,000 inhabitants plus a Class A shipyard (even if it's just for maintenance, rather than construction) is going to come out somewhere around a half a million displacement tons -- or more.
Also, there's an Adventure with events that happen in the Boughene system. IMTU, they don't and can't happen, mostly because I don't feel like running that Adventure... (Nothing wrong with it, but it doesn't fit with what I want to do with MTU.)
The other is
Trexalon/District 268 (extended library data from my "
Collace Between the Lines" thread). Canon says it's what would be an Earth-like world orbiting a gas giant, except it's outside the habitable zone and most of its atmosphere froze and settled as nitrogen and oxygen ices.
My take on it is that it's still Earth-like and in the habitable zone, but is mostly desert, lacks a magnetosphere, and is within the gas giant's radiation belts. The only reason it's habitable is due to orbital geomagnetic field generators (solar powered with fusion backups, multiply redundant with spares pre-staged). The reason it's relatively low-population is that the first set of field generators failed when the Sindalian Empire collapsed a couple of thousand years ago; a lot of the inhabitants are descendants of refugees from nearby Pavabid's revolution that turned it into the theocracy it is now.
Oh, one more: Collace/District 268 -- it's in the late stages of a terraforming project started by the Darrians about a thousand years ago. They also have what amounts to a Class A Starport on nearby Inchin, but it's only there for final assembly of ships out of components built on Collace. It does not affect that world's starport class, despite every effort by its
soi-disant "Baron" to claim otherwise...
