We all have been bothered from the prefects, one day or the other. Each time you hit Sheldon or another kid, they all immediately run to you, even in a hidden place. We must admit that the Bully trouble meter is not so good... I've just bought the game Scarface (The World Is Yours) and I discovered in it a real better system for trouble. Here is how it works :
All the system works with visibility. When you make trouble, it grows a bit. If you are near of an authority figure, it grows (because you are more visible). But if you hide, it goes down. The visibility meter is around the mini-map. If it's full, you have to lose them in time (I mean, become out of reach). If not, then... You fucked up, and then you're killed in seconds. In Bully it could be the time when all prefects run to you ; so it could have a sense, because they all know where you are (visibility).
What do you think about this system ? I tried to be precise, but if you need to know something about it, I'll write it.
