I recently realized that the Japanese names for random girls were kind of a minor irritant. Not because they're not beautiful names, but simply because I have dificulty keeping track of them. I guess my brain's just not wired for it. It's even harder now that the girl list can be sorted and I can't rely on their order anymore.
So I went through babynames.com and picked out a bunch of mostly-western girl names, 463 to be exact. It's about half the default name file's size, but there's much less "Nijika/Nijiko/Nijimi/Nijino/Nijiyo" in it, if you know what I mean.
Of course, it's all personal taste, and there might be some dissonnance on account of all the Japanese-style art in the game, but hey, if you're interested, there you go. Just open your "Resources\Data\RandomGirlNames.txt" file in a text editor and paste in the contents of the "names.txt" file I've attached below. You can leave the default names as well if you want to. The files are simple text with each name on a single line so it should be hard to mess this up.
