The actual execution was a mess, but Skullface's inspiration for his parasite weapon being the experience of linguistic imperialism as a child was a really novel premise. The idea that he would get his revenge by creating a weapon that killed anyone who spoke English is some cool super-villain shit I don't think I've ever encountered before. "Race-selective" weapons, genetic-targetting weapons, religious indoctrination viruses, I've seen all those, but I think MGSV is the only time I've encountered a weapon that targets a language community.
I’m genuinely shocked he didn’t face backlash if some kind. The game does a really good job of showing the horror of American policy just letting that speak for itself. The moment you use binoculars and see the chase for the first time is powerful
