Biggest redpill I can give you: "Phantom Pain" is partially inspired from "Jaya - Mahabharata". 80% of aspects of story and characters match the "Jaya - Mahabharata". It's a partial adaptation.
Here's a trailer of theory for anyone that denies it: Huey is Ashwatthama, he literally has knowledge of all weapons and he literally kills a women and children and he's spared instead of being killed and exiled in the end.
The thing I don't like about VRMMORPG anime is that they're unrealistic. I mean, we know we have a lot of ping issues, latency, and desync. Would be funny if you shoot a player and they immediately teleport somewhere because "ha, your internet suck!".
