What's most remarkable to me is that these percentages have held steady for pretty much the entire time the poll's been up (more than a month now). From when there were only 50-60 total votes to now, there've only ever been variations of 2-3% and IIRC the rankings (T20-CT-MT-GT-TNE-T4-Other) have never changed.
I've been quite surprised at the poor showing for GURPS:Traveller, since one would get the impression from SJG's JTAS site/boards that GT is far and away the most popular system, with CT a very distant second and everything else (including T20) statistically irrelevant. I kept assuming we'd see GT's numbers rise dramatically, and they have a little (it was hovering around 7% for a long time), but nowhere near as much as I'd have guessed. So either GT fans aren't even bothering to visit this site, or deep down inside most of them still prefer CT or MT after all. I wonder which is correct.
I've also been suprised (and a little gratified) by the relatively strong showing for MegaTraveller, considering that 1) it's been oop the longest of any system listed (remember that CT is currently in-print), and 2) every edition that's come out since (TNE, T4, GT, even the CT reprints!) has, to one extent or another, tried to use the fact that it's 'the anti-MT' as a selling point. If Marc Miller is still pretending MT never happened and planning to use T4 as the basis for T^5, I'd hope these results might give him pause.
