The issue with basing the ending off of the 2 characters is I can promise you a lot of people that did that raid had literally no clue what Nier Automata was and just picked the 1st option. It is pretty obvious that is what happened given the server breakdowns.

The fact the devs never realized this is just amazing to me. They just act like everyone has played Nier before and jump straight entire some alternate ending out of nowhere,
