Well, true, it is a little glib.
But really this whole debate reminds me of the stuff the founding fathers of the Catholic church were thrashing out between 200AD and 600AD.
I never played Traveller in the 80's, or 90's, so I don't have that same history of understanding that long term players have. You could say I'm a 'born again' Traveller player. But I do recognise in Traveller something distinct and seperate from all the other sf games out there.
Lets examine some
articles of faith.
1) 1 week jump.
Changing this is the most severe
heresy, akin to denying the virgin birth. However, given that the OTU would change in nature if this were so, but that you kept everything else more or less the same, you could still argue you were playing Traveller, as opposed to Star Wars or Spacemaster.
2) Aliens, like Vargr or Hiver.
Adopting aliens from other properties, like Hutts or Klingons, would not necessarily stop it being Traveller, just as excising Aslan and the rest would not stop it being Traveller. In fact, I could easily see a way of making chargen tables for Starfleet or the Klingons, using the Traveller ruleset. A sort of hybrid game, but something implied in the original CT products.
3) Thruster plates. Well I don't have MT. As far as I can see, CT never mentions thruster plates. Essentially gravitic thruster plates seem to be theological sophistry inferring them from the ship build and operation rules. This goes on all the time in Traveller, most often in rationalising crazy UWPs.
4) Hard Science. This is the strongest aspect that is part of Traveller as a concept. Though it is not total or consistant. However, there is a tone of scientific conservatism that pervades all of Traveller; that the wackier ideas from sf are toned down or not included. This might also be an understanding that such ideas often break or change the game, so as to turn it into something else. Where such things have occurred in the OTU, such as Virus, they have been contraversial and divisive.
I think in reality, it can be any of these things. You are playing Traveller if you say you are. To take the religious analogy further, both Christianity in all its forms and Islam share far more than they diverge from each other, but no fair commentator would say someone claiming to be a Christian is actually a Muslim or vice versa. Zealots and fundamentalists might. There's evidence from these boards that there are such elements inthe Traveller community too.
Rather than define: "What is Traveller?", how about asking...
"What is
Orthodox Traveller?"
