OTSs have a lot of people at the start of the edition, then in two or three weeks the population drops off. Real Tibia holds a steady number of players constantly. If you counted the earnings of all OTS in a year, you could probably compare it to CipSoft, but it's spread out over hundreds of OTS admins. Ravendawn had a good start, probably from January it earned 10% of what Cipsoft earned in a year, but now the game is dead.
