MMO to offer female players in-game discounts

A Russian developer, Nival, has revealed that the female players of the MMO game, Prime World, will be entitled for discounts in-game purchases. In order to make sure that they won?t be getting raided by people who are just trying to get a few discounts, they will be making a mandatory Facebook login. Nival wants to attract player?s ?sisters and girlfriends? who may not play as much.
