It is a Sim, not as crazy as The Sim game from EA, but it is still a sim game. Which already being explained multiple time throughout this thread, also no it is not like VR Kanojo or AI Shoujo/AG3, you controlling girls this time and dictate their action. There is still a free H mode which you do quick sex yeah, but the main game is a sim, the girls will attend their job (nurse, idol, office, casino owner????, student) with each job have their own map and events, there is also room map for girls, the girls will come back to their room after their work is finish, also other neutral map like Coffee shop.
Anyway it will not be a big open world like Sexy Beach Premium, AG3, AI Shoujo, but rather small map. However the girl and other character will operating in those map, do their work and you can initiate events in those map
