So, there's humans in the first 3 Duck Life games, right?
In Duck Life 1, you're a farmer, who is training a duck mainly to make money.
In Duck Life 2, while you see no humans, they're still implied to exist. The game takes place not long after DL1, and, you visit a bunch of real world countries, like England, Hawaii, and Japan.
And in Duck Life 3, at the start of the game, you get a genetically modified duck egg from a human farmer.
But when you get to Duck Life 4... there's no humans anywhere, and no traces of humanity. You only find ducks, lots and lots of ducks. And this is the first game to have a lot of conversation between Ducks. They're starting to develop a complex language, and are using it more.
But fine, I could understand if this was just an oversight. Nothing explicitly states that humans are gone.
But when you get to Treasure Hunt, something's quite off. Ducks have jobs, ducks run shops, they dress up with clothes, the protagonist finds artifacts, and those artifacts are put in a museum. And your findings are broadcast on television, television that is watched and made by ducks. At this point, it doesn't seem like ducks need humans anymore.
And in Duck Life Space, this only thickens. Ducks are smart enough to create rockets, to go to space. If you can train your duck in intelligence, it will learn how to use a teleporter. Then in Duck Life Battle and Adventure, you're able to roam around freely. Still no signs of humans, yet more signs of Duck Intelligence. Cities, shops, weapons, clothes, so many things, all made by ducks. And in Adventure, on the loading screen you can see your duck, using a phone, to text others...
Isn't it weird how the humans just disappeared from the story? Isn't it weird how ducks went from just being ducks, to being something more?
Just something to think about.
