I usually never track those numbers at all. I just remarked on the potential coincidence that the userbase has dropped below 13k right after new year.
I also know this isnt the first time this has happened, and I also remember when people used to say that this game would be dead if the userbase dropped below 15k. But here we are, MANY years after these comments, people still deeply care about this game and we won't leave anytime soon.
