"Not my Genre, Not my System"
That's a really interesting point.
I look at myself, and over the years I've played dozens of game systems (plus editions). At this point I both own and play far fewer. Over the years I've simply pared down what I have on hand to what I enjoy and have returned to over and over again. I play a variety of genres, so that's not my problem, but systems...
I'm certainly not against trying a new system - I've done so now and again - but I'm more likely to invest my cash in ammunition for shooting as I am in a new rule engine. Especially since, over the years I've watched the edition iterations and extinctions savage games I have liked and would have played more.
If I want scifi, I have pickyourversionofTraveller or the same in RTG's Cyberpunk..
For fantasy I have AD&D or, really, these days, D&D 5E which my group is enjoying immensely, and for horror I have Call of Cthulhu or Witchcraft/Armageddon (or, I could not sell my various Pale Pooch games like I keep meaning to) - not counting the new Delta Green game coming out or the new edition of CoC - both of which look like good systems.
If I peruse my shelves, there is also GURPS, ACKS, Space Opera, Fading Suns, Mechanoids, Dresden Files, Victoriana (plus Airship Pirates), The Morrow Project, Boot Hill, Gamma World, Empire of the Petal Throne, Celtic Legends, Blue Rose, Tunnels & Trolls, Ars Magica (1st Edition), Thieves Guild, Artesia, Pendragon, Elric, Psi World, Theatrix/Ironwood, Mercenaries, Spies, & Private Eyes, and Justifiers - plus all of the odd books that I ought for a "cool idea" or to other wise steal maps, or some other content for one of the games I actually play.
I could swear that I have In Nomine buried someplace as well, plus Rolemaster and MERP- and my son is the keeper of Dark Heresy and it's related games.
Yeah, that's the "pared down" list of games.
Most of the gamers of "my generation" have similar, though perhaps not quite as extensive, collections (I worked at a game store for a few years). I also generally the Referee, so I get stuck having to buy anything I want to run as well as anything I want to play.
For me, the issue is not "convince people to play Traveller" it is far more that I need to be convinced to run Traveller - and I'm a die-hard Traveller fan who's been playing since 1979 and has invested hundreds of dollars in the various editions, plus buying old stuff to flesh out his collection...
Some of the points made are right. Traveller used to be a sexy game. It stopped being that a long time ago, and it's been a very, very hard sell to new players. Mongoose has made that much easier - and with their non-3rd Imperium materials people can see that the system has "legs" for a variety of play styles. I don't have trouble with people wanting to play scifi, I have trouble getting them to play what they often seem to perceive as an either dead or very limited system.
My players don't worry about what type of campaign they get to play - they know (or learn quickly) that I'm not willing to the game get in the way of having fun. My goal, as the Ref, is to pick a good game engine that facilitates this rather than being an obstruction. I want Traveller to be that game, but I'm honestly just as likely to pick up Cyberpunk 2020 or Dark Heresy or Fading Suns, heck even Justifier if I want to run a scifi game. They have as much "flavor" as the 3rd Imperium (though not the corpus of canon) and my players find their "crunch" no more or no less of an issue.
And they don't have the long, slow-burning romance that I have with Traveller.
