Good advice, but nothing is in the bag yet. I'm kind of waiting to see if the players want to play bad enough to actually start organizing. If not, I am not going to waste my time starting a story yet.
If they DO make it happen, I'm actually pretty excited to run an idea I had for a campaign - one that involves black court vamps... and politicians.
I think it depends on you and your group and how well all of you know the world. If I were to start a group with players that did not read the novels, I would give them a very short overview and start them at feet in the water. As they experience the world, they are going to get stronger, of course. A single rcv is going to be a whole lot of trouble for a group like that, but it is also a lot of fun, I think.
If, on the other hand, all of you know the world you can easily start higher, as other folks suggested.
This is excellent advice.
On the other hand, I think that lower level players actually have to make more effective use of the FATE system and aspects in order to be effective.
A Chest Deep character can kill a supernatural monster in one shot with stacked aspects and creative aspect manipulation. Feet wet characters... not so much.
A standard ghoul could make short work of a group of feet wet characters unless they were prepared. Yes, I know that throwing a ghoul at that low level of a group would be a bit much, I am just making a point.
I do agree that power level should closely mirror the group's familiarity with the source material.
