Recently I realized Tomino put lots of Hindu and Buddhist themes into Gundam, but I haven't seen anyone talk about this. I guess that makes sense, since it's not like the average English-speaker knows much about either religion. Hell, I only know a tiny bit myself, but it's enough to notice certain things.
And there's also the Origin and Aum Shinrikyo connection. That's a whole 'nother big thing that people never discuss, even though Origin makes way more sense as a story/remake when you realize what Yasuhiko was responding to.
I'm just thinking out loud right now, but when I have time, I do want to write about this stuff with more detail. Gundam has so much spiritual and cultural stuff going on that often gets "lost in translation" for fans outside of Asia like myself... It's quite interesting to learn about. Adds a deeper level.
