Full thoughts I posted on another forum that I thought might be useful here since I think this game is really having trouble communicating just what it is. Or rather, Ubisoft is having trouble with it:
The game has been a bit mishandled. It was announced around the same time as Child of Light but did not get near the marketing push that game did. It also was advertised as being this very somber tale about the gruesome realities of war. But that's really not the case. Quite a large chunk of the game is sort of action adventureish. I might even dare use words like "caper." There's even a few comedy segments. The game is sad when it gets down to it, but if you're looking for a game that maybe does more than lecture you on the horrors of war, this might be it.
Anyways, gameplay was never really shown much for this game. It'd say it's a bit of a blend of genres. 3 are most prominent though, and each level tends to devote itself to one or the other. 1st is the adventure genre. These are typical "You need Item X, but it's guarded by Person Y that wants Item A which is guarded by Person Z that wants item B," sort of things so that you end up helping every asshole you come across in order to get a measly pair of bolt cutters. These levels tend to be either for character introductions or as pace breakers. 2nd are puzzle levels. These tend to be the biggest chunk of the game. You're often navigating large environments and trying to figure out how to alter the environment so you or NPCs you're in charge of can progress in the level. Lot of valve turning and sending your dog to go fetch items in these levels. They also often have some stealth elements, where you'll need to avoid patrols or distract guards. 3rd are more arcade / action stuff. Usually in the middle of a big battle and dodging incoming bombs and constantly running. Some of them have what could even be described as boss battles. They tend to get mixed up so you won't get too tired of one or the other. It's pretty well paced overall.
Game is pretty easy overall. It's probably a bit more "game like" than say, Telltale's recent output, but most of the adventure elements are about the same difficulty, so expect more of a console "adventure" game than an old school PC one. There is one pretty big moon logic puzzle though toward the end. Puzzles seem to me to have never really been one of Ubisoft's strong suits, and it's largely continued here. But it's overall pretty fun, just not going to stump most people.
The game is told through the eyes of 4 characters and you'll switch between them a lot. Usually you'll have the dog with you too. The art style is a bit weird at times. Very comic bookish, but more art comic book than superhero. It sort of reminds me a bit of Terry Gilliam's It's generally gorgeous. There's no real dialogue in levels, it's all very basic stuff like names or basic emotes (the cast is varied in language so I think this mostly works versus everyone speaking English or subtitling 3/4 of the game). In between levels there's actual dialogue. It largely works well but a couple characters end up a little short changed in the character development side. One of the 4 in particular doesn't have near the importance to the story or even a compelling character arc and honestly feels like could've been cut without changing much. The music in this is great and used very well. One of my favorite moments is a car chase set to the Can Can. There's a load of well used classics as well as originals.
Anyways, the game is relatively short. Ubi for whatever reason tried to pad the length out with a bunch of collectibles scattered through every level which don't have a ton of relevance. I honestly kinda just decided to ignore them after a while, as I thought they kinda detracted from things. Seems to be a sort of current trend with some story heavy games where they don't seem to think they can hold your attention so they just vomit doodads to collect every 10 feet (recently Murdered Soul Suspect was awful about this too). But even if you try for 100 percent I'd wager you're looking at a 7 hour game tops, if that bothers you. But I think it was very well paced and ends pretty perfectly.
Honestly I'm a bit flabbergasted that Ubi pimped Child of Light over this. I think Valiant Hearts will have more staying power than CoL, which is a game I enjoyed, but largely for the battle system. Overall, get it, it's good. Just don't expect it to make you cry every 5 minutes. But it does pack a wallop when it needs to.
