Other than the furry quotient, though, what does making them mice actually do to the game? Are there implications of scale? I’m thinking – and this is just totally riffing here – that BMG would feature the surviving mice living aboard the BSG, amongst humans, zipping around in ducts and hiding in forgotten crannies of the ships while hiding in cargo to move from ship to ship. I have no idea what happens when you introduce humans into a MG game, though – they’re so big and effectively immortal and all-powerful that they’d probably be forces of nature.
Further riffing on this: do the Cyclons have a second prong in their efforts to discover the secrets of their own souls? Are there in fact Cyclon mice hidden among the survivor mice in the fleet?
This whole angle would allow you to use Nature(Mouse) unchanged from the original rules – they’re still MG mice, and they’re probably even still medieval, but now they’re on ships featuring a whole different set of issues.
