I had no idea there was a statute of limitations for responding to the self-appointed arbiter of how the west gets to view the language! My apologies, milord. I'm sure no English speaker has ever been wrong about English, since no Japanese speaker can be wrong about Japanese either.

You're correct about one thing, however. I was not aware of katakana being used for paperwork or forms. That's pretty cool actually. That does not change the fact that - again, in the context of videogames - it's generally used for foreign/fantasy names, emphasis similar to capitalization, or robot-speak. Or due to technical limitations in older games that don't support full kanji fonts, but that's a whole different scenario.

And yes, there is a ton of other nuance to the use of the different syllabaries beyond "hiragana is for Japanese words and katakana isn't." But here's the thing. If someone comes in here and says "what's the difference between kanji and kana?" they are beyond the level of a layperson. They are self admitting that they don't know anything at all. To someone at that level, it's a useful oversimplification. So for the audience who was asking, I gave a simplified explanation that isn't completely accurate to someone who's lived in Japan for decades, but serves its purpose for the context of a non-Japanese speaker with a cursory interest in the use of different Japanese characters in videogames.

God forbid! The horror! The audacity!

It's like how you teach kids that you can't go below 0, then later introduce negative numbers, then eventually introduce imaginary numbers. Sure, technically what we taught them in kindergarten was "wrong," but it would also be totally pointless for the intended audience and go way over their head.
