Something I've been wondering about is, what does rooms generated actually mean? How is it different from rooms used? Why is this number so high?
I'm not really the best expert on this, but I'll pitch in anyway. Rooms are generated when you create a room (obviously), but a lot of times, you get odd things happening like GM 'generating' 20 or so extra rooms that are promptly deleted.. so I dont know.
Basically, sometimes when you create a room, this number goes crazy.
And because it's so high, we can brag about it. Boo yah!
