That they're "Traveller" is your opinion, definitely not mine. But on the DGP point, you're completely wrong.
I own just about all of the DGP stuff, and no pics are fantasy oriented the way the Ninja Vargr and Cyberpunk Darrian are.
I had all of the DGP stuff, once upon a time. And I stand by my assertion. If they had had such paintings, i believe they would have published them.
However, I have come to the conclusion that this argument is pointless. You have a fairly narrow vision of what Traveller is. If that works for you, and your players, then that's fine.
Your vision does not include anything (or practically anything) that Mongoose does, and that's fine too, if it works for you.
However, to come across like some sort of authority on what Traveller is, and say that what Mongoose is doing is NOT Traveller, that's not fine.
You may have a decent claim to know to what Traveller WAS. However, in the Mongoose era, you clearly don't know (or refuse to accept) what it IS.
Have fun with your game. That's all that is important. But please, stop trying to turn people away from Mongoose Traveller with your intense (and in my opinion) misplaced negativity.
You are entitled to your opinion, and you are entitled to express your opinion. However, to do so as constantly as you do, is not useful to anyone. You act as if it's personal, like Mongoose Traveller is a deliberate affront to you. It's not, as far as I can tell. It's just an attempt to redefine a game in order to drive sales. That's what companies do.
Disclaimer: I don't work for Mongoose. I may in the future, but we shall see. I am under no contract to them. I don't even think MgT is the best version of Traveller, nor does it have the best art. I do like it, but I don't loveit. It is, however, available, playable, and new stuff is coming out. I have purchased several books for it, but I am not a completist. I buy what I can use.
