I like the idea and approach, that its guerrilla fighting emphasis, not squad killing in CoD. Or.. at least thats how it came off to me.
Though I am really curious about what the consequences are. If you're particularly violent in one mission, then the next day does government get tougher? If you spare someone but they see you, will you see wanted posters for you? THings of that nature are what I'm curious about.
Also, they said the massacre fatigue, I wonder how they'll make you care for the enemy. It seems like the only way you could do that is a guilt trip by having each guy have a picture of a lovely wife and kids on his body that your character sees every so often. Rather then have you sympathize with them.
And finally, I like the characters. Particularly Hopper, because it shows the evil. Its not just he regular, "oh, he's a bad guy, but he wants to fight with us, I dont trust. Hey he saved my life, well you're my bro for life now, I dont care if you're the same colour as the people trying to kill me". He has the scars, the reason to not fight with them because he was ostracized and injured due to his race. Yet he doesnt bear a grudge (or if he does, he doesnt let it get int he way of his patriotism/willingness to fight for his country's freedom) and fights with people who by all rights he shouldnt like because the larger portion of the population hates him for his half bloodedness. Its something yo udont see often in videogames or movie, but mainly in story cause you can devote the time to character background and exposition.
Other then that, the game looks atheisiastically good and I like the scope scenes they mentioned so far and how that will play towards the mood and theme of the game.
