Droachmega, are you referring to the achievement league? There was in fact a gaslight league, and I would call it a resounding success!
I did not stick around long enough to find out how many participated, but there were at least a few dozen that I know of.
Note: Sean, your idea for terrain cards is awesome and I plan to implement it (probably to the hisses of our Adepticon terrain masters) ASAP for next year. *grin*
