School and education systems is where a lot of people develope their personalities, likes and dislikes - of which many will be taken forward into adult hood. Or, as I like to call it, ARRRGHHH! So, in my opinion, these kind of role plays are popular because they allow people to recreate more exciting and enjoyable experiences in a school environment. We are all here to experience another reality apart from our own, and who wouldn't want trade in their crappy school memories with awesome role play moments. Not to assume crappy school experiences, but I'm sure we all know some point in our young lives that we wish hadn't happened. You get me? That's my opinion. *babble ends*
