I think the amount of discord in regards to this game is (from my limited observation) when you have two different groups with opposing viewpoints/likes in regards to the content of the game. ie caring path versus the abusing path. There will also be some overlapping people that swing both ways
both sides discussing the narrative, but also I think subconsciously trying to keep safe their side of the game they enjoy.
The fact that NeonGhosts has managed to appease both sides of these groups for the most part is worthy of praise.
Just to preface this next part I play the "good" side of the narrative
The Lucien part feels like to me an escalation in all those TV cop/murder shows that suddenly switch up to bring in and then eventually focus on some large conspiracy involving powerful people when either they feel the audience is getting bored with the regular theme of the shows, or the writers/showrunners are. Some people will be off put with the switch in the narrative focus, regardless of if it was planned all along.
But it's also you don't want the story to stagnate and just be the same events happening over and over again with no challenge happening.
So I definitely understand why the decision to bring Lucien into the game was made, and when introducing a villain into the game where the "Hero" can be a very evil person himself you need someone equal or worse then them. Which just makes them seem over the top to the people who are playing the good person , versus just seeming like an equal to the Evil path players. The extremes of the choices play against the writer in this regards I feel.
I would have loved to have this game continue as a more Slice of Life game, I'm struggling with not being able to continue due to the theme change. However the game is not mine. The most important things is what NeonGhost wants to write about, what he has planned and what he wants the game to be. they have created a story that people are passionate about experiencing and discussing which they should take a good amount of pride in what they have made.
