4. Batarian Ending, Mass Effect.

While this isnt strictly "only mass effect" its a take on how hippies carrying the starchild generation ended nuclear war with the help of ufos occasionally shutting down missile sites and how the shivans and or reapers and or "completley non existent forces that blanks block" would like to turn this into a fallout/demon world and how our choices "in universe" must reflect a desire to avoid this. Perpare for copious amounts of moralizing.
