Well, looks like we definitely have enough people on board to give this a go. So I suppose the important question now is "who is the new villain?" Personally, I'd rather it be a PC, and since we will have a system that allows for combat, we don't have to worry about pvp being a problem. I suppose it is best to let whoever the new villain is choose his role and background. Perhaps he is an instructor looking to gain power now that the Death Eaters have fallen? Maybe he was a new student when Dumbledore's Army formed, and he has been slowly working on members from within and turning it into a bit of a dark cult. Just to sweeten the deal, I will have a slight mechanical bonus for whoever plays our head villain, because we don't want him to be a pushover.
Since this thread remains Wolfy's, I won't create anything. I may have hijacked the planning, but I want to make sure he is okay with me outright hijacking the game. If I do end up running it, I should let you know that I like to do a lot of discussion before starting IC posts. After all, we will be playing chars that have gone to the same school, so it makes sense to spend some time working out which characters are rivals, friends, already dating, or maybe even used to date and broken up.
Seeing as how a lot of this planning can be done while you guys are learning the system, I don't think it will take as long.
As for the system itself, it should be ready for character creation within two days or so, and then I will just need to finish compiling all of the spells from the books into a list with difficulty rating and what type of spell it is. I did some basic play testing on it last night and was pretty happy with the balance in combat so far.
