In a 13+ game it's not teenagers' fault if they're submitted to advertisement for adult content, it's ERPer's fault for advertising to an audiance that is underaged to a degree.
It's actually blowing my mind, none of you were teenagers ? How did we all not lie about our age to get on some adult websites. And now you're advertising adult content to the same teenagers we were, knowing they will happily lie to you about their age just like we did to get on adult websites.
