MgT can no longer be considered canonical for anything but Mongooses settings IMHO
Here are a couple of changes they have made to their ATU
personal energy shields at TL15, with vehicle and ship screens at lower TLs
conscious entities are necessary on jump ships or there is a greater risk of misjump
tachyon canon, ion canon (a direct Star Wars rip off)
Yes, but some of those things I think are detailed there as part of the "generic" Traveller ruleset, and not as 3I setting canon. MgT is still trying to do Traveller as CT was originally intended as a generic SF ruleset that is setting agnostic. What I would prefer they had done would be to have clearly marked some of these things as alternate setting technology.
- Keep the Vehicle and Ship Shields and Screens (since they are common tropes), but note them as not available in the 3I setting;
- Put the Tachyon Cannon and Ion Cannon (and perhaps Meson Guns/Screens) in an alternate technology section, noting what settings they properly belong to or are representative of);
- Same structure for Central Supply Catalogue;
- etc.
