If I didn't get into NieR: Automata, I don't think I would have gotten back into the hobby after briefly leaving it due to college and health issues. I fell in love with the game, and I especially loved the two of the three main androids of the game. When I saw that Volks is gonna make the YoRHa androids into dolls, I knew I had to get them. Except, I couldn't afford purchasing both dolls, so I ended up purchasing 9S first. I just couldn't get over that adorable, beautiful face of his. I fortunately bought 2B few years later though!
I think this was the decision which truly changed my life forever, because ever since I got 9S, well, my BJD collection just suddenly exploded and expanded beyond what I thought. It was that moment I knew this is the hobby I am meant to be in, and I am truly happy I encountered Nier: Automata before then, and taking in 9S!
