For those who mentioned the seemingly inconsistent tone of the game I think it's absolutely integral to the message of the game that for every 'win' we experience during the narrative (be it the taxi sequences, Baron battles, etc) the overarching tide of the war itself doesn't work out in anyone's favour and leads into the ending of the game. Which is not to say it was all meaningless, but that those small wins don't compare to the great losses suffered.
Of course I suppose this is just opinion and all that. The game wasn't perfect, but it was important to the game that we experience humour and joy (whether that was in a comic fashion or down to earth) for the serious moments to have greater impact.
I agree whole-heartedly. If this game was emotionally somber, down in the rut (trenches?) the whole way through, the frankly ludicrous logic required for puzzle games would have stood out starkly against the narrative. Instead, the developers have injected plenty of playful humor and Saturday Morning Cartoon drama into the game, that allows the player to more easily accept the game mechanics. Personally, the musical/driving sequences were a standout. Montpellier did a great job marrying gameplay to music in the Rayman games, and they've carried that knowledge with them in Valiant Hearts. The scenes have a Disney-esque quality to it, where action and song are merged to capture the artfulness of musicals.
This hopeful joy is, of course, contrast with the grim reality of war. The historical facts contained in the game are, by and large, heart wrenching. Similar to Art Spiegelman's
graphic novel
MAUS, the artstyle and the rays of levity are interspersed with brutal death. I think the game could have gone further with the contrast, but by and large Montpellier restrains themselves until the final act, a decision which can make the first 3 Acts feel a little too much like a chicken chase.
In the end though, Montpellier gets it right. UbiArts is one of the best recent developments in videogames, and I really hope we see more of this smaller budget creativity. This game, alongside Brothers and The Walking Dead, makes a case for videogames as a strong medium for interpersonal drama.
