Video Game: Professor Layton and the Curious Village
The first game in the Professor LaytonWidget Series.Layton and Luke search through the eponymous St. Mystere for the Golden Apple, which was hidden there by the late Baron Reinhold; the will of the baron states that whoever finds it will inherit his immense wealth. Of course, the village hides quite a few secrets as well...Please place series-spanning tropes on the main Professor Layton page.
This game provides examples of:
Abhorrent Admirer: Martha, an old woman with a lisp Layton and Luke meet on the way to the tower.
Artificial Human: Every single character, except for the recurring cast, Bruno, and Baron Reinhold. Matthew, at least, was a real person at some point.
Batman Gambit: Baron Reinhold created the whole village so that only somebody clever and caring enough would discover his fortune and use it to care for his daughter. Unfortunately, there's the chance that a clever man would get to Flora, then a caring one would be led to the treasure. This in turn creates the chance that Flora would be stuck with a greedy - but smart - Jerk Ass, and no money. He might have been assuming that a Jerk Ass would just ditch her when he found out there was apparently no money and she could go back to waiting for the right person, but that leaves the question of what they'd do with a person like that to keep the village's secret from getting out.
Bruno was there to watch people entering the village, to make sure they were morally worthy of finding and caring for Flora. Additionally, an evil clever person probably wouldn't have made Flora happy, and therefore never found her "birthmark" or the location of the fortune.
It backfires slightly, though. By finding someone kind enough to care for Flora, he accidentally found someone too kind to claim her inheritance and "kill" the village, leaving her to make her own way without it.
Of course, once Bruno snuffs it, and he's getting on in years, the village will run down of it's own accord since there will be no one to repair the robots; after that, there's no problem with claiming the fortune. Of course, this was always a problem all along for the gambit. What if Bruno had died before Flora became of reasonable age?
Captain Obvious: If you tap on the stairs in the inn, Layton says, "These stairs lead to the second floor." You know, like stairs do.
Cats Are Mean: When Luke tries to pick up Lady Dahlia's cat, it scratches him clear across the face and runs away...which requires them to go chase after it.
Closed Circle: St. Mystere, starting shortly after the game begins.
Due to the Dead: Baron Reinhold had an elaborate tomb built in the garden for his first wife, Flora's mother, so that she would always be close by. It's unclear how long he lived after her death, but the pages of Bruno's journal seem to indicate that his excessive mourning contributed to his own early passing.
Easter Egg: In the "Painting Scraps" tutorial, if you look closely at the sample painting that is in the process of being pieced together, you can see that it is the picture of Professor Layton and Luke from the cover of the game.
Foreshadowing: When Layton and Luke meet Flora on the top of the tower, they learn that her father told her that the person who solved the mystery and came to get her would be someone she could trust with her life. A few minutes later, when Layton, Luke, and Flora are fleeing from the crumbling tower, the stairs collapse and Flora nearly falls to her death... but is pulled back in the nick of time by Layton, thus proving her father's words correct.
And prior to this, while Layton and Luke are climbing the tower, they have to solve a Klotski puzzle called "The Princess in the Box." The puzzle's description urges the player to help the princess escape from where she's being held.
Fortune Teller: One of the villagers, Agnes, insists on reading Layton or Luke's fortune in exchange for their solving a puzzle. She invariably predicts bad luck.
Getting Crap Past the Radar: At one point you are required to look for a clue in the painting of a girl. Touching the general area of the breasts will result in a comment from Layton. Because of the proximity to the place where you are meant to touch (which is made obvious), it's entirely possible to find this accidentally.
Professor Layton: Now, Luke, it's important to be a gentleman.
Gilded Cage: St. Mystere is essentially this to Flora, who can't leave until a worthy guardian solves the mystery of the Golden Apple.
Insane Troll Logic: The candle puzzle. You have three candles remaining because you let the seven lit candles burn down until they were gone.
Insistent Terminology: Characters constantly refer to Layton as a detective; he gets just a bit annoyed at this, since he's actually a university professor of archeology.
Insufferable Genius: Layton to Pauley, who constantly gets beaten ahead from solving whatever puzzle he hadn't solved yet.
Interface Spoiler: If you look up the details on the "Vanishing Crank" mystery as soon as it's listed as "Solved," it will give away the fact that the true purpose of the will was to find a suitable guardian for Flora shortly before it's revealed in the plot.
Obstructive Bureaucrat: A benign one of these can be found in the town hall, pestering Layton about paperwork and telling him it would be wise to leave town once he finishes his business.
Old Retainer: Bruno's journal pages seem to imply that he sees himself in this light.
Real Men Wear Pink: Though not exactly a Badass, Gordon implies that he'll be stuck with his stuffed animals, kittens, and ribbon candy for the rest of his life unless he finds a girlfriend anytime soon.
Robo Family: A few different kinds of robo-family relationships are present in this game. There's the aforementioned Dahlia, who is a robot spouse to the baron, as well as Simon who was built into the Reinhold family. Then there are a few families in the village.
Robot Dog: What you get once you've picked up all of the "strange gizmos" in the village. It sniffs out hidden puzzles and hint coins.
Soft Glass: After Layton reveals that "Chelmey" is really Don Paolo, he exits Reinhold Manor by smashing through a closed window.
Solve the Soup Cans: Justified, as much as this kind of plot can be justified, by the ending: the many puzzles are to ensure anybody without an above-average intelligence wouldn't ever reach the top of the tower.
