I should have expected the game will be shallow, I guess the adventure tag got me fooled.
The story ... i don't mind story being generic but there is lack of explanation, causation and emotion. Nothing is being explained really, starting from the fact why you want to be royal knight ending with what makes one Dark Queen ? There is lack of build up and causation - things happen because they need to happen, you only learn character can do X when the need for X arrives. The only real consequence in the game being that after helping busty lady you get scene her. The story of no importance to the main characters other than "someone wants to destroy the world" and none really ever shows like they fucking care about that. When you are name dropped to be Heroes and need to stop Dark Queen everyone moves on with it like it was the most natural thing in the world.
Characters... they got big boobs and you are not supposed to care about anything else.
The combat... when you make option to halve or disable the encounters you already know that the encounter system is shit. The thing is that monsters populating the map is part of world building, you make the world more alive, more believable. So the best part about combat is that you can skip it and traversing the maps is the most boring experience.
