What's the backstory if you don't import a save?
What are the default starting conditions for new characters (non-imported) in Mass Effect 3? I would assume this question has come up somewhere before, but so far I haven't been able to find a concise answer.
I already read so much that the game assumes you made the dumbest of choices in ME2, so Jack is dead and no romancing Miranda in ME3. But what are the other conditions to look out for?
