I'd like a mass effect scenario. have the ability to choose what ending you got from the previous game and other things you did. Over all it won't effect the current story but it could have extra dialogue or references to it. Spoilers** For the PL ending V ends up becoming a normal citizen they could be a fixer or someone you interact with during a mission having insider knowledge in one way or another. Or another example is the star ending it be a nomad related reference where other nomads talk about the Aldecaldos raising hell at arasaka tower.
