From around 2 weeks ago I started and finished this game. Found it to be a great VN.
The game system to be very fun. The system may be easy if you just take as many turns you want, but the biggest challenges is to conquer the countries on the "incorrect" order (means fighting first strongest ones when possible, which gives you special items and makes the other enemies stronger) plus the hard mode you unlock if you get the true ending. The interface patch really helps to play too. There is a group translating it now and they expect to release it in around 8 months.
The art is very beautiful, and the characters design are cool. There many events with and between characters, doing a good job of developing the relationship between the main and the girls and also between the girls themselves. The cast is very big, there is a total of 71 female playable characters, plus 1 non playable. The story is nice although without much surprises in the middle, but with a very interesting twist around the end.
For anyone interested, a full list of the female characters in the game:
