I played the game through, and I'm on my second playthrough now. I really enjoyed the game itself
and I get why people disliked the ending. I am playing through again, however, because apparently if your EMS (Effective Military Score) is >7,000 you get a teensy tiny sneak peak at what the ending really is...or isn't.
I would suggest that the rest of you join me just for shits and giggles.
Also for optimal EMS:
Did I miss any?
