I've noticed I have these "box" type items in my inventory which can sell for some decent money. Should I sell those or wait until I get further in the story? And another thing, the chick with the glasses next to the female quest DJ. What type of system/business is she giving your party? Lv. up stores etc? Plese help.
"To each his own." I can't read kanji but I'm still playing the game because it's interesting to me. For you it may not be worth the investment, but to me and the topic creator, it's a worth-while investment because for us it gives us enjoyment and a challenge.
Suggestion: if you are going to play games in Japanese, you should, at the very least, learn the Katakana. It takes minimal effort and it helps a lot to just be able to recognize a few terms, like names of items, places and people. Even if you can't read Hiragana or Kanji, many times you'll be given a hint of where to go to or what to do because the dialogue refers to a certain name, or you'll actually have an idea of what an item or a skill is.
Of course, it's not universal, but it's certainly more convenient than opening a translation guide and having to compare the translation with the chicken scratches on the screen.
