I recently asked a question about undead having darkvision.
I felt that the original question was pretty unambiguously worded, but apparently I was wrong as the answers don't really match what I was looking for at all. I've asked a related question on Sci-Fi and Fantasy SE, which was almost closed. This question is focusing on my curiosity regarding other media.
I think I should delete the original question here, and write a new one that is more clearly worded, making it clear that I'm interested in the reason behind the game designers decision. If this happens to be other media, great, if it happens to be an in-universe justification, great, if somebody did it for kicks, great. I'm just curious why, as it seems like an extremely odd decision to me.
Does that sound like a reasonable course of action?
