A Shared Universe means that all of the creators involved with it are contributing to it
The following are the rules/guidelines/suggestions for dealing with this.
- The tone and direction of the universe are set. While there is room for infinite expansion within that, we are not going to change what has already been established. Evolution will happen. For an example, there is room for anything from a grim, gritty, depressing Noir style story to a blue-skies, optimistic feel-good story. There is not room for something that completely ignores the boundaries of reality and exists on slapstick or extreme parody/satire.
