Have you been pleased with the feedback for Joshua Graham? I've replayed Honest Hearts 2-3 times just to soak up his relentless charisma and have been happy to find a modest collection of fan art going for him.
As much as can be expected. A lot of players really wanted to see the Hanged Man/Burned Man incarnation from the Van Buren design documents, so I think most of those people were unhappy with how he turned out.
I had wanted to develop a religious conflict in an RPG for a while, one that wasn't presented as pro-religion vs. anti-religion. I didn't want to use a proxy/fictitious religion and I didn't want to use religion as the set-up for a series of jokes. My first idea for Honest Hearts was a direct conflict between Joshua and Daniel where Joshua was more like his pre-fall self, but I didn't think the characterization would be particularly interesting and I didn't think players would struggle much with the decision of whom to support. It didn't take long for me to change the main conflict to one about Joshua and Daniel vs. an external threat, with the player's choice revolving around which leader to support. I think we often present players with a choice between two bad solutions and we ask them to decide which one is least bad. With Honest Hearts, I wanted the player to decide which solution would produce the most good.
I wanted the player's first encounter with Joshua to be very reductive. In way, I wanted the player to be initially disappointed. They hear legends of this fearsome, terrible, demonic figure and when they first see him, he's doing the equivalent of putting his pants on one leg at a time: sitting at a table maintaining a stack of guns. Even internally, some people complained about his appearance. They wanted him to be huge and monstrous or they wanted his first encounter with the player to involve him brutally gunning down White Legs. I believed that for his character to feel right in the context of the story, he needed to be a man first and the monster later. But that expressed desire on the team made me ask for the graffiti players see on the way to see Joshua: an entire cliff face dominated by the image of Joshua with tiny White Leg corpses falling down below him. In the image, he's like Goya's Saturn, dwarfing and destroying everyone around him.
Presenting the conflict with Daniel posed some challenges because Daniel is not a living legend, i.e. he is even more of a normal man than Joshua is trying to be. Additionally, Mormonism is not a pacifistic religion (and its soteriology does not depend on pacifism), so the conflict could not reasonably by framed around violence vs. non-violence even in the post-apocalyptic version followed by the New Canaanites. Daniel's concern was about larger issues than fighting or not-fighting; he was concerned that Joshua's lapsed nature would cause a whirlwind of warfare that would pull everyone far away New Canaanite traditions to the point where religion was virtually abandoned in favor of a war cult surrounding Joshua.
I had expected that most people would support Joshua, in part because of Joshua as a character but also because of the nature of gameplay in Fallout (i.e., violence is almost always a solution). I did not expect that the Survivalist's logs (written by John Gonzalez) would push so many more people toward supporting Joshua. I think it's an interesting example of players finding their own connections between the two stories and making an emotional connection that pushes them in a particular direction.
