Take all the investigation skills and put them on a central team sheet for everyone to draw from.
I’ve been thinking about shared player resources an awful lot recently. The idea of a ‘party’ has been knocking around since day one, but for non fantasy gaming, it gets a bit strained at times. Even in games with squads or teams that the setting supports, the individual character sheet seems inviolate. There are exceptions of course. I was really impressed with the ‘party’ card that WFRP3 used, which gave out abilities for everyone to draw from. I also like the Marvel Heroic mechanic where heroes become more or less effective if they’re in teams, buddied or solo.
So for Gumshoe, which is really two games welded together by the use of a d6, why not really separate them out? That way everyone gets buy in on the investigation parts, no one feels like they can’t contribute and the resources are shared. General abilities stay under the purview of the individual player.
Am I mad?
