I got to thinking (I know, dangerous) that we might be able to get a feel for how many players have signed up for this game.
I signed up in mid January. My number is 5947. If that represents a numerical counting of players that have joined, then some more recent joiners could enlighten us as to how many have joined. Earlier players might confirm if this progression of numbers is real or not. Comparing against current player base might offer insight into long term viability of this game.
