We won't have to worry about the unisystem itself since I'm only taking the things I want to use from it out; such as elements of the character sheet, and the bare essentials of other things. Nobody will need to download the corebook, or worry about reading anything but what I provide for this game. Unless they want to, of course.
To be honest, I only have the one corebook for Witchcraft, and it's the only system I understand; mainly because they provide a free download of it on DriveThru RPG, and I've played, albeit a small game of it in the past. I'm really trying not to make this too complicated, since I think more than a few players in this game have no experience with system games, and only really joined this one because the one I had up was easy cheesy. Also...as this dives deeper into a 'real system' game, my confidence that I'll be able to GM it successfully goes down marginally.
So far, I have all the blank character sheets for each district written up, and the number of Character points that will be available. I'm working on which skills will be available for everyone, and which bonuses a character would get for being from a certain district.
The dice system will remain a d20 one, and I'm going to try to make it incredibly easy. This last part is what's giving me the most trouble, because honestly, I don't want to run it like a regular system game, where I have to give everyone the results of each of your rolls. I want this game to pretty much work self sufficiently, so if I'm gone for a day or two nobody will get held up.
I will throw this out though, if anyone wants to Co-GM with me, and help with the whole system aspect of this game, than I'd welcome a volunteer.
