Ubisoft have shown more of Valiant Hearts: The Great War, the charming art style looks to be giving the game a lot of character. Set in WWI they seemed to be going for a heavily emotional story. The trailer focused on a dog reminiscing about his fallen comrades. Even with the art style Ubisoft seem to be taking the game very seriously. Putting such an emotional trailer after two dudes doing push up seemed like an odd choice.
I do have to applaud Ubi for making a game that seemingly has a lot of emotion intertwined with it.
