Not a Game

""Selling books is like a game; it has rules, and you have to learn them and get serious about them because it's not a game!""

- Evan, Black Books

A Stock Phrase used on characters frivolous—or apparently frivolous—in the face of a Matter of Life and Death.

"This isn't a game." or "We are not playing a game." (Or sometimes "We are not playing.") Sometimes even when it is a game, but the stakes are too high to treat it as one, such as the second type of Serious Business; alternatively, the character may point out about the game "This is serious," generally with an enumeration of the consequences. (With the first type of Serious Business, use of this is a characterization trope: the character is really that out of touch with reality.)

Often supplemented with concrete observations, such as that people will really die or suffer terrible injuries if they fail. Sergeant Rock (who knows War Is Hell) will often use it on New Meat that think War Is Glorious.

Usually used on people who are supposed to be on the same side as The Hero, and who are cooperating, but not just seriously enough. Cavalier Competitor is a natural target for it. The Obstructive Bureaucrat, for instance, usually gets told just that this is a Matter of Life and Death.

When this is news to the character, see And You Thought It Was a Game instead.

Sister Trope to This Is Reality, but with no invocation of the Fourth Wall (unless, of course, it's being said within a Video Game). You Watch Too Much X is a milder Sister Trope. Compare with And You Thought It Was a Game.

Anime and Manga

 * In MAR, the evil Chess Pieces have created a War Game where the last remaining strong good guys can fight against them in a final struggle for the fate of the world. When attacking the land of wizards, Kaldea, the Big Bad Phantom comes across the protagonist Ginta, and fights him off without any effort. As said fight was not during the war games, Phantom let him live, saying that "today's fight was just for fun." Ginta promptly goes berserk, exclaiming that it is NOT a game.
 * Digimon
 * In Digimon Adventure, Tai gets pretty reckless after he learns he's in Cyberspace, thinking that the Digital World's only virtual and there's no real danger. He's eventually set straight that it's as real as Earth, with no extra lives or continues, and has a Heroic BSOD over how his recklessness could've killed him.
 * Ken, however, mistakes the Digital World to actually BE a game in Digimon Adventure 02, not knowing he was enslaving real beings and, upon his defeat and before joining the group, threatens to "reset the Digital World".
 * Also shows up in Digimon Tamers. After learning that Digimon are real, Kazu and Kenta think that being a Tamer and fighting evil Digimon is the coolest thing ever. When they want to accompany Takato to one of these fights, Takato nixes it, invoking this trope.
 * Speaking of Pet Monster series, Pokémon did this trope as well. In the episode spent in the Orange Islands, the Team Rocket tells the twerps that "this isn't a video game?"
 * Summer Wars is about an A.I. hacking into an online virtual world that the real world uses for nearly everything. When the protagonists try to stop it, their families gradually realize the activities they have been playing on their handheld devices isn't exactly a game...
 * In Naruto, Kakashi Hatake berates Sasuke, Sakura, and Naruto for not taking their training seriously enough. He even says, "You think this is all a game"; he makes a point by holding Sasuke hostage and giving Sakura the option to either kill Naruto or he [Sasuke] dies. After explaining how dangerous the shinobi world can really be, and how many lives are lost from mistakes or childishness, the trio finally get what it means to be "a team".

Comic Books

 * A number of DC Comics fans relate "This isn't a game" immediately to Batman and his various Robins, given how often this phrase is uttered between them (or from one Robin to another). Specifically, Jason/Robin II is linked to the belief that it's a game; meanwhile, Steph/Robin IV yelled at Black Mask, before he beat her and started torturing her, that "this isn't a game!"
 * When Cerebus Syndrome sets in during the 4th volume of Bone, Gram'ma Ben tells the innocent Fone Bone, "Where do you think you are?! Back in Boneville!? It's high time you realized that this isn't a game, Bone!"

Fan Works

 * In With Strings Attached, when George asks what happens if they can't get a piece of the Vasyn during their quest, Jeft tells them that “this is not a game you can win on good intentions and points. You have victory conditions....” The other Fans think he's just using gamer terminology, but the irony is that  and is actually quite true.

Film
"Mrs. Incredible: Remember the bad guys on those shows you used to watch on Saturday mornings? Well, these guys are not like those guys. They won't exercise restraint because you're children. They will kill you if they get the chance. Do not give them that chance."
 * The Incredibles:

"Hopper: You think this is a game? Well, guess what: you just lost."
 * Megamind. Titan has no use for banter or jibes. He is just a murderous, brutish thug.
 * A Bug's Life, when Hopper comes back and the ants have not collected all the food yet:

"Sue Charlton: Mick -- be careful. This isn't a game. Mick: Tis to me."
 * Inverted in "Finding Nemo" : at one point, the only way that Marlin and Dorey make it out of a dangerous situation without completely dissolving into panic is by pretending that it is a game.
 * Crocodile Dundee II. Mick Dundee is about to go up against some gangsters.

"Sean Davidson: This isn't a game, Gavin, those were ninja!"

 * GoldenEye:

"Ruth: This is not a game. Our situation is precarious. You know the money's gone. Rose: Of course I know it's gone! You remind me every day!"

 * Titanic:

"It's not just a game -- anymore."
 * In Magnolia, while he is participating in a TV game show, Stanley's teammates stress that this isn't a game.

"Sark: FINISH THE GAME! Flynn: NOOOOOOOOOOOOOOOO!!!"
 * Tron: When Kevin Flynn plays his first game, he at first has fun, but when he realizes that the games are to the death this dialogue describes it all:

"Unknown program racing against Clu: It's just a game! Clu: Not anymore. (kills his opponent)"
 * The teaser trailer for Tron: Legacy plays a variation on this:

"Bishop: Ah, Jesus Christ, you just... You don't just trade these people like they're baseball cards! It's not a fucking game! Muir: Oh, yes it is. It's exactly what it is. And it's no kid's game either. This is a whole other game. And it's serious and it's dangerous. And it's not one you want to lose."
 * Spy Game. Inverted. Clue is in the title:

"Johnny: Oh, come on! We just said this is serious!"
 * The tagline for the infamous Super Mario Bros movie was "This Ain't No Game."
 * Fantastic Four: Rise of the Silver Surfer: Right after Reed Richards explains that Johnny Storm's encounter with the Surfer earlier in the film has caused him to begin randomly swapping powers with other members of the team whenever he makes physical contact with them, Ben Grimm grabs Johnny's shoulder and knowingly causes their powers to switch.


 * The fact that it's Johnny, who is usually the jokester on the team, who says this only further emphasizes how serious the situation really is.


 * Hard Candy: "Jeff, playtime is over. Now it's time to wake up."

Literature
"Rawne: I'm not playing around because they're not playing around."
 * Dan Abnett's Gaunt's Ghosts novels:
 * In Only in Death,, Rawne informs his officers to tell the men that if they slip up, they will make  sacrifice in vain. When they are shocked:


 * In His Last Command, when Gaunt orders Ludd to leave him, and Ludd objects that his orders were to stay with him at all times, Gaunt answers that that was fine when it was just a game, but it wasn't a game any more.

 * In The Lion, the Witch and the Wardrobe, when all four Pevensies swipe coats from the wardrobe to wear in snowy Narnia, one of the younger siblings suggests they could pretend they're Arctic explorers. An older sib points out that their circumstances are already exciting and mysterious enough, there's no need to pretend anything. Not quite a Matter of Life and Death, but same trope.
 * Subverted in The Black Jewels Trilogy, in that to the Sadist, it is a game. Near the end of the series, when Daemon's not quite as cold-hearted to everything, the phrase he (and other characters) use to tell themselves they've got to keep going is, "Play the game," or keep the deception against the Big Bads going. Similarly, when witnessing an Arcerian execution, one character says, "He [the huge intelligent tiger] is playing with him [the man to be executed]." Another character replies, in a grim, low voice, "He's playing, but it isn't a game. This is an Arcerian execution." The tiger then proceeds to precisely, brutally, mercilessly murder the man by batting him around as he would a toy. Considering said tiger weighs in at around 800 pounds, the man lasts about a minute before being gutted and left to die as everyone else watchs. In case you're feeling even the slightest bit sorry for the guy, the reason for the execution was Don't read that unless you have a strong stomach or you don't visualize things as you read them.
 * In Terry Pratchett's Only You Can Save Mankind, the Captain criticizes humanity for thinking all of life as a game. Later, during a class discussion of the war (Iraq, then ongoing), Johnny hears someone asking whether they think the pilots treat it like a game, when they could be killed at any time, and saying that people turn everything into games and it's not games. Then he realizes it was him.
 * In Shanna Swendson's Don't Hex with Texas, Owen tells Dean that magic is not a game.

 * Chuck. Casey to Chuck, after the latter (a Geek Squad employee) claims he can defuse a bomb:

""Best of the best. Counting kills, like it's a game. Like it's just a game. I remember one particularly fun day: A guy in my squad got his stomach blasted open in a fire fight. He spent six hours, holding his own guts in. His buddy carried him on his back to the nearest aid station, just praying that someone could put the dumb son of a bitch together again. The game, Pyle... the game is played with your buddy's life -- with the life of your squad, your platoon. The game is played by you, on behalf of the whole damned human race!""
 * The Sarah Connor Chronicles has Shell-Shocked Veteran Derek Reese thrust into a mentor position for a bunch of teenaged military cadets, who talk about their aspirations. He does not approve.

 * On one Sidequest in Mass Effect, Shepard has to convince a woman to stop working as an informant because her sister is worried about her. At one point, Shepard says "This isn't a game, Jenna. These people are dangerous!" which I found amusing because, you know, it is a game.

 * In Jak 3, the monk Seem tells Jak and Daxter "This isn't a game!", and they respond by giving a side glance to the camera.
 * Quistis says this in Final Fantasy VIII when Rinoa comes up with yet another hare-brained scheme right before an important mission. Rinoa's response, to herself, is "Who said this was a game...? I understand what's going on... It's not like I don't have a plan..." And later, when you control her-- "I'm not a SeeD, but... I can do this... This isn't some kind of game..." Squall essentially paraphrases it even earlier in the game after having directly dealt with the consequences of her hare-brained schemes over and over, leading him to finally snap.
 * In Persona 4, teen detective Naoto Shirogane drops by the main characters to inform them that the murders they have been investigating have apparently been solved, and that their 'game' is about to end. Of course, by this point many of them have either lost friends or nearly been killed themselves over the course of the investigation, and they angrily point out that if anyone thinks of it as a 'game' it would be Naoto, not them.
 * The very first line spoken in Wheelman is "You think this is a game? Move!"
 * A Cut USA General from Command & Conquer Generals: Zero Hour has lines left over in the game's files. Amongst these is "What? Do you think this is a game? Well, do ya?"
