Not my screenshot btw but I hunted it down after playing through this part. I've been playing it for a bit now (I'm on path C) and it's still not 100% obvious to me that it's an explicitly pro-leftist, though there are some hints. For example, there are also 2 robots named Marx and Engels, where Marx dies early and you talk to Engels as a side quest. I'd love to hear what your thoughts are on this game if you've played it before.
Broke: Liking Nier Automata because it tries to be brainy
Woke: Liking Nier Automata because you're a Platinum Games Character Action Goblin
Bespoke: Liking Nier Automata because Yoko Toro is weird and worth keeping an eye on even if most of his stuff is kinda bad
I just realized this is my opinion on Hideo Kojima as well.
Regardless what you think of Kojima or Yoko Taro at very least their games are kinda different and somewhat unique from most mainstream games.
