Quite a few people played Erbana, but when you look at the percentage pie of all the routes combined, Erbana was the smallest. After the Ending, that percentage dropped to near non-existence. Kind of tells you what type of population survived the Ending...
Sidenote: Realistically, altruistic people did survive the Ending. But this is two years after that. Most of the purely unselfish ones have either died trying to save others or are too devoted in their quest to help others to even bother with the Game.
Also, I'm traveling today so comments may be slow in showing up.
