The Dev really needs to think about shortening the size of this game
I think this is the biggest issue with the game taking so long to complete. The Dev seems to go off on tangents with creating a huge cast of characters that are unnecessary to the story. The more characters inevitably lead to more resource/time spend developing their individual stories and this takes time away from actually progressing the game to its conclusion. We've also seen endless recasts/revamps of characters who's personal stories have changed going through the versions of the old game, to the versions of the revamp. Many of which are not particularly essential to the plot anyway.
For me the game focus is meant to be the MC's 'new life' therefore the family characters, the mafia characters and some of the school characters/teachers should be the limit to the NPCs that the MC primarily interacts with. If the dev wants to expand the world beyond that, that's what sequels are for.
Its debatable whether this is deliberate, so the dev can drip feed their paetron until the end of time with all the loose ends they've made. On the other hand, whether the dev just doesn't have a very focused mind. Who is prone to rushing ahead with ideas before considering the implications to the main plot.
