Chulip is a regular small town with a kiss-based economy. Solve peoples' problems and you can kiss them. Some of them live underground, one of them is an onion, another's a talking utility pole. It's a town composed primarily of weirdos.
Also the town's sole policeman will murder you if you stay out after dark.
Dolphins run the world while humans travel to the stars in golden bubbles (naked, mind you), as aliens throw themselves against a magical force field that protects Earth. But then it fails and Ecco time travels to save the planet from the aliens, which includes going inside the queen.
In Mystical Ninja the strangest (and best) element is the giant ninja robot. You spend the entire game playing something sorta similar to Ocarina of Time, then you stumble upon a robot that just so happens to look like exactly like protagonist Goemon, only it's 60 feet tall. Then you climb inside and it becomes a punch-out style robot combat game.
Suzuki Bakuhatsu is a surrealist game anyway, but it’s a place where a young woman will answer her door, find a package with an orange inside, but the orange is a bomb and must be peeled to be dismantled. At one point, she finds out the moon is a bomb and has to diffuse it.
The world of The Neverhood is a place where everything is drab brow, made of clay, and aggressive bands of apes with bare skulls for heads wonder the land making fart sounds ... which is normal in sections of New Jersey, but pretty weird everywhere else.
A strange alien planet one inhabited by a race of avian-like creatures that apparently had so little trust in each other that they made almost every door a ten minute puzzle. Now we know why Samus is so good at critical thinking and survival, finding the refrigerator growing up must have been a challenge.
A 1950s styled cyberpunk world infused with humor that pokes fun at historical real-world Cold War fears.
Jazzpunk has a stack of strange references, including a nod to Hunter S. Thompson. You run into a character in a hotel who is Raoul Duke, the writer's fictional alter-ego, who says a mix of random weird things to you.
A cult-favorite, Beyond Good & Evil captures the imagination of fans to this day, each of which hope its sequel (announced in 2008) will one day return us to the far-flung future mining planet once dominated by the evil DomZ. We really just want to hang out with Pey'j again.
The other levels are all based on over the top ideas - velvet paintings, monster movies, a disco. But the milkman level is just a neighborhood ... filled with G-men who are really, really bad at disguises.
punkrawkbbob: "Discworld was a profoundly bizarre and rich world, but is also based on books I found out afterwards ...the world exists on the back of a turtle, you have a roaming chest that follows you on feet, dragons exist only because you believe they do. ...It was a really bizarre game but incredible on some level. Think it was my first tryst with satire/spoof so that helped endear me to it."
MauricioAldecosea: "I know this probably is a bit strange, but I'll put forward the world of GTA as a weird and wonderful one. Part satire, part celebration of unrestricted id, part condemnation of that very same id, the world of GTA is at once removed from reality and slightly too close for comfort. Characters tend to be horrible, selfish, almost psychologically deformed creatures, and yet it's not hard to see aspects of people one knows – or of oneself – in them."
