Dankeschön, Lord TMA! I don't like to see a good sticky thread go to waste
Right, so,
Duck Game. The deceptively simple appearance on the surface may make you think it has less depth than it really does. The gameplay could be described as a mix between Worms and Super Smash Bros.. Each round is won not necessarily by whoever plays the best, nor whoever kills the most other ducks, but simply by whoever is still alive after the smoke clears (if anyone
is still alive after the smoke clears). This, combined with the typically very short lenth of the rounds, makes death feel far less like a penalty. Unless you're a very serious player who confuses "fun" with "winning", I can't see you being likely to get angry playing this game. You're more likely to just laugh at the silliness of the death. Penguinboy's custom title springs to mind: "Haha, I died again!"
Behind all the inanity, however, there's more than just a mindless laugh factory, and if you indeed are a serious player, that doesn't mean you won't get your fix here. The gameplay is very well balanced, with a lot of different ways to kill someone, and also a lot of different ways to defend yourself. Everyone starts a round evenly with no weapon; sometimes you'll all be spread over the entire level, sometimes you'll all be right next to each other. All levels have a different spread of weapons and layouts, and your approaches will have to adapt to suit. You might be on the level where everyone starts next to a sword and a suit of armour; do you pick those up and just try to hack each other to death, or do you try to make it to the single magnet gun in the middle and pluck people's swords right from their wings (or, indeed, latch onto the suits of armor with the ducks inside and drop them over the edge)? Maybe you've got a choice between the risky grenade or a trusty pistol — which one will do the trick on that duck waiting for me on the other side of this wall? Sometimes it all comes down to reflexes, but not as often as you might expect. More often, it comes down to your tactics. To be honest, besides Worms and Super Smash Bros., this game scratches the same itch as TF2 in a way I can't quite describe. Oh, and there's Worms Armageddon-esque challenges for singleplayer, if you're into that kind of thing.
Oh, and I almost forgot. There's a quack button. It makes you quack. It single-handedly distils every laugh, taunt, expletive and cheer into a simple, humble sound expressing so much more than it itself. Whether or not it's better than a voice is up to you, but I'd take a humorous little quack over a squeaky 12-year-old any day.
If I have anything to say against it, it's that a number of game-customising features are currently exclusive to local on-the-couch play. According to discussions I've seen on the Steam Hub for it though, they're working on extending them to online. Playership also seems a little low.
tl;dr:

completely irrelevant to enjoying yourself.
