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.
