The obvious pros of this game: Tons of characters to meet and activities to do, the scenes are varied and have plenty of options to pick from..
The devastating cons: It takes a decent amount of grind to really get into the game and enjoy it's content while at the same time, certain decisions can't be undone, like who the current main love interest is. And certain major characters get this overpowered ability that allows them to know exactly whom the MC is dating and whether he is in a serious relationship or not, you feel like the dev himself is cockblocking you and acting like a divine protector of the realm he made so to speak. And because the game requires a significant amount of time to unlock it's full content potential, most of the people who played it at least once before don't feel encouraged to do multiple playthroughs to explore other character routes, so when an update is focused solely on one route, for many that counts as a delayed release.
