How is that good news... No, what about the other game? The one where we give full 100-99 discount vouchers upon starting, isn't its sales terrible?Looking puzzled, the secretary said while anticipating the boss's reaction: They've been shouting things like 'what a conscientious company' and 'if we don't spend, they'll go bankrupt,' so they just topped up. That game sold a whopping one hundred million copies globally. Congratulations on making a billion!“......”At 3:30 a.m., lying in bed, Ke Jin was wide awake, unable to sleep.
