I don't read a whole lot of manga. It's why I don't talk about it too often. I watch way more anime, and I play way more video games than I read manga. That's why they pop up more.

I really enjoy stories about androids. They may be done to death, that I'll give you, but I'll just never get enough of seeing how an AI could gain sentience. I just won't. It's the little wannabe philosopher in me that enjoys these stories about humanity so much.
I liked NieR: Automata a lot. Like a lot, a lot. Even so, I could still sit here and tell you many ways the game was unpolished. It was far, far from perfect in regards to the gameplay, that is. This was but one of my numerous experiences with this game's oddities. That one was pretty fun, though.
