We have just begun our first campaign in Blades in the Dark. We normally play more D&D(ish) type games that are very heavy on rules, dice rolls, and having every detail of the world already in place. In those cases I have always chosen to have someone else run the campaign, someone who is more of a rules lawyer and likely to remember every tiny little detail that applies to each and every situation.
I LOVE the face that Blades in the Dark is based more upon the story and narrative than it is upon rules and regulations. There is enough information given on the world to be used comfortably (should you choose to do so), but also so much left open to the imagination.
As I have a great love of story telling and was incredibly impressed with the potential that I saw in this game, I knew that I not only had to have it...but also that, for the first time in over ten year....I wanted to be the one to run the game.
I have banned the rules lawyers from my game (there are one or two that are still allowed to play, but they understand that they will be playing a very different style game and they need not refer to their rulebooks as I may choose to bend or alter some basics at times if it suits the story and situation).
We have only played two sessions so far, and while I did choose to start with the general idea of the quick start campaign I have added an interesting twist that seems to have the players totally intrigued.
In short: We are still getting the hang of the game and the rules that do exist within the game, but we are loving both the environment and the concept and in spite of my nervousness about running a game while being so out of practice i'm getting rave reviews on both the game and the story that I am weaving for them. I expect we will be having a great deal of fun with this for a long time to come.
