The backstory makes it out to be a more or less life-defining decision which faction, Enlightened or Resistance, you select.
As far as I can see though, there doesn't seem to be any real difference, except for color, between the teams. Is there any difference at all, and if not, do we have any kind of hints, or maybe educated speculation, on whether that might be planned in the future?
Or can I just flip a coin?
