kinda kills the whole "Vault Tec + American consumerism parody" theme
I personally don't mind that too much, because the storyline of the games never really revolve around this.
It's just a theme in the background, an explanation for why America was like it was when the bombs fell.
Playing through the last three games, I've never felt that American Consumerism is a significant aspect of what I am seeing/doing at the time.
And as far as Vault-Tec goes, I feel like there's nothing new for me to discover. I enjoy Vault-Tec and the vaults, but I know their background, and that things weren't as they seem.
I wouldn't mind seeing the Chinese communist alternatives, which surely there were similarities.
Enough so to maintain the core gameplay and style we've been used to. Plus, there would be American aspects too, since they were in a war with each other, and Americans landed in China, and even took some cities prior to the bombs falling.
