Events: One plugin or many different

Hello,
I'm actually writing a big Event (A Player has to kill Mobs and gets Special Drops and so on)
Now my question: Is it bette to do everything in one single plugin, or to differ it, so one plugin for killing the Mobs and another one for the Things, the Player can do witht this Drops?

 

@Typ
It's all up to you. But I'd recommend you a single plugin, so when you make a update for one, you wouldn't have to check the code of the other one for errors (if you know what I mean), and you also won't have to post two diffrent files which would then have to go through security check.

 

Yes, I think you're right with the first Thing, to the second one: I write it for a Server, and we won't ever post it somewhere
Thank your
