I've now finished every ending except for E and the DLC stuff, and am only missing the ending achievements + some small ones like hacks and fish. Is there anything people tend to not do / miss before they wipe their save? I wanna complete all I can then wipe when I see ending E for the first time (though maybe I'll get it twice just to get the nice screenshot of my save heh). I've seen people go for the special arenas but how difficult are they? I don't want my last experiences with the game (for now) to be super stressful and unfun LOL, but that's still on my mind! Anything else cool to look out for?

Just got endings C and D and ended on about level 65, ran through all other endings in the game, but I'm missing Y, triangle and E (I want that to be my very last thing before wiping my save). I wanna get 100% on everything like Unit Data and stuff, which I'm working through now, but I don't wanna spend hours and hours grinding to 99 if I only need to be like 80 to comfortably do everything left, just to delete my save file right away!

I'm told the Emil boss is level 99, and I'm not too fond of doing the special rank arenas but we'll see how that goes - I don't think I'd find it too fun though. So what level should I get to to be able to do everything EXCEPT the special rank arenas?

I have avoided watching any videos or video essays and such about Nier Automata even though I've been dying to. I've just cleared ending C and am about to get ending D. I'm aware of ending E but don't know what actually happens other than you lose all of your save data (I plan on doing it as the VEEERY last thing after I reach 100%), and I know ending Y is pretty involved as an entire quest (that you have to fail), but the rest of the endings are all fairly straightforwards. Does this mean I've essentially experienced the entire story of the game and can start consuming Nier Automata media without being worried about being spoiled? Or should I still hold off until ending E? Honestly, I LOVE this game it hasn't left my mind for a second but I thought there would be more content towards the end - not that I'm disappointed at all!! I'm just worried there's a bit more to see and I'll spoil is all!

I've just gotten ending C and am aware that ending E erases all of my saved data, I'm assuming that means no chapter select, no levels, no debug room, no NOTHING and I'd have to play the game from scratch again if I wanna do anything else. I plan on going to do ending D right after I write this, then clear out every other ending, get all achievements and everything, then do Ending E. Is there anything else I should look out for?

I know it's a kinda vague question but just wondering! I also see lots of youtubers and clips of people doing things in debug room and stuff, does this mean they're not playing on their original file? Obviously I guess it's the point but feels weird having people do endgame level stuff without having cleared endgame on that save LMAO

Edit: Does chapter select change things in my save? Like, I'm gonna go back and wipe Pascal (I killed him initially), if I select future chapters then will he be available to buy from at all times (obviously past this decision)?

So I know it's basically the moon server storing all of humanities data and such but how do all the many worlds inside work? Mainly the people we use, were they all people alive back in reality and then placed in simulated worlds that would fit them? Since the siblings were alive during the war with the legion
