I don't think it will be viewed as irrelevant by Sony or Square Enix. Besides Bloodborne didn't sell much better and is still very relevant to this day. In my opinion is no game that sells over 2 million irrelevant especially if it represents a mediocre popular genre.

Nier Automata has sold over 1.5 million to be more precise.

As of May 30th.

It could be at 2 million.

Wtf, this game REALLY REALLY blew up. It's insane. It  has sold like 500k on Steam alone. It was like at 350k a few weeks ago. Physically it's probably a little above 1 million. I'm guessing it's probably at 1.5 mil on PS4 including digital.

NieR: Automata

Chartz Sales: 0.96 Million
Actual Sales: 2.00 Million
Difference: 1.04 Million

スクエニ<1>:
-ドラクエ11は300万本超、「概ね目標は達成。今後さらに積み増す」
-NieRは200万本超、「予定の倍、ダウンロード比率も高く嬉しい誤算」
-FF15は660万本近くまでいっている。

0.96m + PS4 digital sales + Steam sales (estimated at 600k by Steamspy) + shipped copies not bought by consumers yet.

Sounds like accurate tracking to me.

He is spamming a lot of old threads, some with obvious pc sales being the difference. Like LA Noire.
