None of my new players have heard about any kickstarter. They ask me what version of Traveller we were playing, after the first session, and they go an buy the Mongoose books so they can start refereeing games. None of them visit any Traveller forums. Forums are dying out. These are the 20-year-old crowd, using their phones to watch videos of Traveller reviews.
Yeah, I'm not 20 at all, but when I realized that the e-version of T5 was only available on CD my first thought was "how archaic." Why isn't there a PDF version of T5 available on RPGDriveThru?
One proven way to increase exposure is to remove restrictive copyrights. Of course, that has it's own drawbacks like where to find funding for the next release if the popularity doesn't increase. If it does increase, however, people will buy - or donate if they have the option and the popularity is strong. (I doubt anyone would want to risk this, however, having just managed to get T5 out the door.)
I think there's a players handbook being worked on (I might be mistaken). If there was a bulk discount (which would make good sense to allow groups of players to buy their own copies and not have to share) then someone could buy a bunch and donate a single one to several different thrift stores.
Someone was working on an iPhone app game for Traveller. That would likely work quite well.
Add random scan-able bar codes in RPG magazines for people to scan with their phone and get a page where they can download a Traveller ship with art work and deck plans (and a link to purchase T5, of course). There could even be a challenge to "get all 12 ships" by sending in the UPC of the magazine you find the code in (send in via taking a pic and texting the image to a number). Once accomplished you get a Capital ships info and an adventure that uses at least a few of the ships. There could be 12 such rewards but only allow one per phone number so kids have to compare notes to see them all.
Create a Traveler's Aid Society in all major cities in the US (and Canada too....don't forget about me) designed to promote Traveller. Certified member get 5% off purchases of T5 products.
Commission a statue of Mark Miller and erect it in front of Wizard's of the Coast headquarters.
Create a watered down version of T5 that gets distributed on a cheap flash drive to gaming stores everywhere to be distributed for free, or very, very cheap (most kids can't drop $75 for a book...especially if they don't have any idea what it's like).
My local gaming store had no idea T5 was out there, which is why I bought it online. I didn't even know about the kickstarter project until a couple of days ago when I realized there was a new version out there. I think the first step likely needs to be to let people know it exists.
Oh, one last idea. Freelance Traveller is a free publication....is it available at online stores (like RPGDriveThru)? Distributing a free magazine like that would likely go a long way to promoting awareness. A local Traveller's Aid Society leader could print out several copies of it and give it to local shops for distribution.
Anyway...I'm just brainstorming here. Many of these ideas might have already been discussed. Apologies for any duplication.
