See...I'm not crazy at all about that cover with the Ninja Vargr.
Is the art good? Yes.
Do I like the cover? If we were talking about a different game, yes.
But, is it Traveller? No.
It's a good pic, but this game is Traveller, not Star Wars.
Ah, we've been here before - the art (and feel/atmosphere of the art) in Traveller has to change. The style of the characters and, to an extent, the ships is very, very dry in the older editions. Purely my opinion, but the only one of the races from the Classic era that even comes close to looking contemporary is the Zhodani.
The Aslan and Vargr were quickly designated as 'needing work'. The Darrians were desperate for it (and we'll be interested to here what people think of our interpretation). Someone here described them as 70's glam rock rejects, which was hardly the atmosphere we wanted to portray.
As for the core Traveller book, and concentrating on the second printing for a moment, I think one thing we might 'clash' on is whether it 'feels' Traveller or not. The thing is, we were going for no feel in the core books other than generic science fiction (and not always hard sci-fi), purely because we wanted Traveller to be a launchpad not just for the 3I, but for other settings too - we did not want to lock it down into any one sub-genre or setting.
As for the layout, as others have pointed out we wanted it to remain very functional and utilitarian, as well as mirroring the Classic range.
YMMV as to how well we did. However, we are finally educating people as to the breadth Traveller can carry in terms of setting, finally divorcing the game itself from 3I - we always knew that would take time. The upshot of this is that Traveller support is starting to accelerate rather than spiral downwards, which would be the natural state of a game at this stage of its lifecycle.
