I wonder about your Saturnian ring scenario. Where is the moon relative to 
the ring system, and how do they interact with each other?

The ringed outer planets do have moons, but they do not appear to 
measurably affect their planets.

Discussions I've seen of the role of our uniquely large moon (in absolute 
size and particularly in size relative to its planet) suggest that life as 
we know it would not have developed here had we not had the Moon.

And would the ring system have a tidal effect? If so, how would it compare 
in magnitude and direction to the lunar tidal effect?
