To run SWADE deadlands here should I have both the SWADE core rules compendium and the Deadlands compendiums, or is the Deadlands Compendium sufficient. I'm going to guess both are useful/needed because of the edges and skills in the SWADE core rules that aren't in the Deadlands, and then the rules changes/new skills edges in the Deadlands rules. But I just want to verify before I drop the cash on compendiums.
