I'm not sure I've ever felt this detached from my characters in an RPG before. None of the characters feel like they're my own, even though I made them all from scratch.
That seems like a design decision they made when they have you choose different personality traits for each of your characters. If I recall an interview by the designers accurately, they wanted to make it feel like a real tabletop experience with people arguing and interjecting. The downside is that it removes the player's agency to direct at least one character. I guess they were thinking "hey, what would a game with full party creation be like if you had party banter like you do with NPCs?" I don't know whether they're satisfied with the result, and I wonder whether they'll change that if they make a sequel.
Which I hope they do, because for the most part the game is good and definitely shows promise. If the modding tools continue to get better, I think it'll be around for quite a while.
