An extremely amazing game truly unlike anything I've ever played before. Valiant Hearts adds a human element to the game that is missing from a lot of these war games that we see and is a fresh break from the whole "Kill kill kill" mindset you need for those games. The majority of Valiant Hearts is done through puzzles. The player needs to find ways to navagate around in the game, and do it by using their smarts rather than their trigger fingers. There are indeed parts where you do attack the enemies (you have to so they don't detect you and end the game), so it isn't just puzzles. Each of the characters are very likable and have their own unique stories, motivations, and reasons for getting involved in "The Great War" - and the best part is that those reasons, like these characters, are all believable.
Valiant Hearts also does well in capturing the nightmare that was World War I, and does it without graphic depictions of blood, gore and violence that is prevalent in games set in war. In the final chapter of this game the full scope of exactly how brutal and bloody this whole sordid affair was becomes obvious (there is a part where you have to take cover from machine gun fire by hiding behind solid cover- a few piles of dead soldiers are used this way at one point). There are also many very interesting facts this game presents about WWI that most players may not have known, so history buffs and fact lovers are going to be in for some good info. In my opinion, it is not only good to see a game that is set in WWI when most game studios seem to prefer WWII (perhaps it is because of the "noble cause" of the allies in that conflict), but Valliant Hearts takes both an unflinching and unapologetic look at the first World War and presents something as vile as trench warfare in a manner that is much more palatable than a shoot 'em up sort of game would have been.
Just a heads up, though: Valiant Hearts FORCES you to download and install UPlay. This is a fact that is not READILY visible on the store page unless you have enhanced Steam (which I do not). While that fact may not have prevented me from getting this game, I just don't want to HAVE to download a new DRM console every time I get a new game from a different publisher.
