Everybody agrees, that the game is about opinions, changing them and mass hysteria, but the most interesting point is the main character you control. Somehow, most of the comments come to conclusion, that the grey is the middle-ground (often seen as the best) point. I think it is NOT.
I see the main guy changing his opinion, standing against crwd, not because he only whopes to get people on his side, but more importantly, because he wants to argue, get in the conflict and challenge others. The process of brain waves communication is the important one.
I think, finally the guy gets grey not because it is the truth. If mrX OR mrY said something about missG, if you make a compromise and say, that noone said it, it doesn't make your compromise true. If the game was in colour, the character might as well got green or pink or sky blue, it doesn't really matter. For him matter only to be AGAINST someone and argue, challenge, persuade.
P.S. Brilliant game, loved it, keep it comming
