I set the video game "Torchlight II" to the German language, and I noticed that the characters use "Ihr" as the singular second-person pronoun (for example, "Ihr habt eine neue Quest").
I read elsewhere that "Ihr" was used as the formal singular "you" a long time ago, but has since been replaced by "Sie". The game takes place in a somewhat medieval era, so would that explain why they use "Ihr"? Does other German media that take place in the distant past usually use "Ihr" as the formal second-person pronoun, to match the time period, or is there another reason for this?
