Every once in a while, as a mod, it's a good idea to do something out-there to get your game buzzing. This tutorial is about how to run a few game-wide plots that virtually everyone in your game can participate in. The world of Harry Potter makes it pretty easy to do crazy things. There are also some general High School ideas and some Marvel ideas too. These plots help shake things up and give people an excuse to act out of character once in a great while. Don't put these plots right on top of each other, but every couple of months it might be a good idea.
The first thing you need to make sure you do is make an OOC announcement making it clear what is going on and that participation is optional. Nearly every game has that one player who thinks that everyone is out to get them, so make it clear that nobody is being forced into anything, but this is an opportunity for plot and fun!( Harry Potter Ideas Here )( Marvel Ideas Here. )( General High School )
