Ending A literally ends with the huge implication of this being a cycle, among leaving millions of questions unanswered. It intently withholds 2B’s character, but unsubtly lets you know “keep playing there’s more to your lame waifu”. There is nothing satisfying about the ending and it's pretty clear you are supposed to continue. Sure, it's like a typical story...if a typical story did'nt want to explain anything at all.
And you may think it's whack as hell, but I dont. It was extremely pointless in Nier A and serve no reason for being there other then "I guess the two other games I made have it and people like it". But there was nothing clever about it this time and the story would have been better serve being told in a far more direct and linear way. Instead of me losing complete interests because hours later you are retreading on connections from a previous chunk of the game that I've moved on from and am now playing though on a character that is garbage and makes me want to break the disc. Oh but hacking.
You make think it's fine, but I don't. Instead of having stand a lone chapters meant to be built around comparing and constractsing the revelations or stories that the previous chapter you played, you get story routes like B where you spend time playing as 2B doing pointless stuff just to get to the actual meat of whats going on. Compared to a well paced multi perspective story that could keep the momentem of whats going on. You get a game that waste plenty of time, because it thinks it's clever.
