Here's the thing: In theory, based upon those expressing a preference, the generl selection of traveller potential fans should look something like the ratios on any given traveller website's fora, provided the fora are not subset restricted.
(IE, yu can't count FUDGE Traveller Nuts on this board, since there is no section for "Homebrewed Traveller Flavors".)
GURPS is underrepresented... but GURPS is also divisive amongst grognards... some love the details, some find them nuissances.
That we odd few are so decidedly FOR a digital version, and also are interested because we still are making new MT players from scratch.... that's telling. That many of us essentially decided that nothing post MT has been "valid", well, that alos is telling...
But MT was brutally killed by GDW... in favor of a mechanically very distant cousin... yeah, it borrowed a bunch, but it was no longer a "Clear Descendant" in the same way that Supremacy and Advanced Civilization are derivatives of Risk... Supremacy uses the same basic ideas, but civ is wholly different ideas for the same goal: being the most powerful nation in the world. That all later editions have ignored MT, it is amazing such a high percentage of us still use it as our primary traveller.
(My ideal traveller is essentially MT with T4 psi, and T20 trade and commerce.)
