These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Atelier Rorona: The Alchemist of Arland
Die for Our Ship: rabid Sterk/Rorona shippers shows this tendencies towards Meruru for turning Rorona into a little girl in Atelier Meruru. After the game is out and the 'real' culprit is known, they attacked Astrid instead.
Fan Dumb: Japanese fandom (more specifically, the creepy ones) suffered one when a screenshot of Tantris and Rorona talking to her parents was surfaced. They thought he's Rorona's ex. The truth is far from that.
Fan-Preferred Couple: Rorona/Cory for Les Yay fans and Sterk/Rorona for straight fans. Both of which might be canon at this point.....at least until Atelier Meruru comes.
Fridge Logic: Putting a log, some mushrooms, and a jar of what looks like urine in a pot and stirring it for a day produces a fruit pie, pan and all.
Game Breaker: Tera Bombs, especially the ones with good quality.
for playable characters example, Sterk and Gio. Justified as they're more experienced in combat than anyone else in the party.
Cory's "Call Servant" skill is another one.
Iksel. He's accessible early in the game, doesn't cost much to hire, has effective special attacks, and is one of the few healers in the game. And unlike Lionela, he has a high HP cap.
Moe: Rorona. Most of her popularity in game stems from this.
