Most popular titles on this ladder.

I am not sure that you can equate popularity with the number of reported games; the oldest game, S41, leads the list. You probably need to incorporate a factor to account for days on the market, and another factor to account for the number of other competeing titles on the market. Such that, when S41 was released there was no other competion, but when M'44 was released, there were many other PzC titles out there. So time on market and # competeing titles needs to be considered. Of course, the more precise way would be to simply organize a poll.
