Froglet won't outnumber Backgammon... my guess is it will grow just a little faster then Battleboats Plus - and probable settle in there around the Backgammon Race or Crowded Backgammon level in it's popularity. (again, just my guess.) :-)

I've always kind of measured it by the number of people who have a established rating. But then it is hard to judge games which have not been here for awhile - so then it would probable have to be something based on started games or something
