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.
Expy: Anna could pass as a white-haired sister to Saber.
They Wasted a Perfectly Good Plot: The game is quite bad at this. Not only the story could be resolved more and better around the Uroboros and the Alterworlds. Also but most of the characters aside of those in the main quest hardly get any characterization at all with the main exceptions being Winna, Alvero, Rufina and potentially Phenyl.
They Wasted a Perfectly Good Character: All characters in the main page had full potential to become party members and hold the tradition of a six member party in the Atelier Iris games, but you only get three instead, possibly due the fact Edge and Nell gain other Blades (forms, or classes).
Squick: Pukko enjoying being beaten up by Phenyl; also, the obsession of a sprite with Repre was- disturbing to put it mildly.
