Its AA3ish, dialogues have been expanded as well as new interactions and jobs among other new content, also now there are more details such as the characters sitting around the map, actually eating at the cafe and more animations for gestures and reactions.
However, the map is small, the AI behavior needs more work, there are no teachers, the map can hold 12 characters (Up to 24 but the map is too small for that) and there is bad performance.
It seems like can be fixed, after that will be very decent, becoming somewhat better than AA2, but there is a lot of room for more content and improvement. They even announce 8 more personalities so, having a bigger map seems possible.
