When you remove the context of the thing she's referencing, yes. It's completely arbitrary.
It's not just NA version. As I said, they are a boke & tsukkomi duo (
Manzai). It's a style of humor unique to Japan that doesn't always cross borders gracefully. Humor is the whole point of their interactions in all versions of the game, regardless of that their in-game professions are. That particular style of humor simply doesn't have the same impact on Westerners as it does Japanese audiences. I don't mean to be offensive, but if you didn't recognize that Callie liking chips was a comical reference, it only proves my point that this type of comedy and the jokes they make in the Japanese version likely went over everyone's head outside of Japan.
If you ever take up learning a second language that has a different root than English, you will see what I mean. I studied Arabic for 3 years. During that time, I learned that, with languages that have nothing in common with English, literal word-for-word translations are not always helpful because they don't really capture the meaning of what is said. The translated lines themselves are easy to understand. The nuance or colloquial meaning gets lost in literal translations. Second, as stated before, you also have to know what they are referencing to get the joke. If you don't get the reference, you may not even realize they made a joke in the first place. Third, Japanese wordplay only works if people read the sentences in Japanese. If you translate them, the whole gimmick falls apart because it relies on how the language sounds. So, there's another genre of humor where non-Japanese speakers will completely miss the joke and translations won't help.
This is my whole point. You didn't know what they were referencing because what she referenced was something only Japanese audiences would get. Yes, chips exist all over the world, so I'm sure everyone knows what they are, but that statement is making a reference that likely went over the heads all non-Japanese players. Thus, the whole point of saying she likes chips is lost. The NA localization team recognized the whole purpose of that statement was to be funny, but it wouldn't be funny to Americans because they wouldn't get the reference. So instead, they changed it to something US players could better connect with.
Now back to our regularly scheduled theorizing.
Can Inklings get sick? Would "human" viruses still affect them?
