Welcome to the vocabulary section. The words are going to be divided by series (even though the pictures make it look like it’s by game) with a miscellaneous section for games that I didn’t write down that many words for. Just because a word is in one section doesn’t mean it isn’t in one of the other games. In other words, try to go through all of the lists to get a more comprehensive vocabulary. If you study a few of these words a day along with your regular study schedule, I think you’ll have an easier time jumping into gaming in Japanese.
