One thing that stands out to me in Crystal Clear is that the writing and "quests" in the storyline are actually good. Even Nintendo/Game Freak has a lot of trouble with this aspect of the games, getting stuck in the same old "2 B A MASTER" and "THE WORLD IS ENDING" tropes. One of the parts I noticed this most was in the Pokemon Mansion with Eusine. Though, even in the intro with ShockSlayer talking I already could tell the writing would be better than we get from ROM hacks most of the time. It's serious, but not stereotypical or annoying.
