Traveller could disappear off the face of the earth forever and nobody but us few would care, look at even the biggest of the game companies such as Paizo, with a value of about 11 million, that is tiny. For example, I built single family residences in California that cost around that much or more and I was a executive for a mid-sized Design Build that had almost 300 employees. Traveller nor Mongoose had any presence at Gencon, I only learned of Mongoose from CotI, my local flgs has not heard of them.
How many of us are there, maybe 4000? Which is a number I heard bandied about and it could be far smaller. The point is, play and have fun, everything else is irrelevant.
