So, our hero has just given the blacksmith or healer some [[ElementalCrafting unobtanium]] or [[FindTheCure rare plant]] he gathered from the far reaches of SlippySlideyIceWorld to make into something he can actually use in battle. The NPC tells him it will take a while "so wander around and come back."

Our hero, ever impatient to get on with his epic quest, comes right back inside after walking out, probably to bug the NPC with taunts of "Are you done yet?" Amazingly, the NPC is not only finished with the commission, he asks what took our hero so long to get back.

This is a video game trope in where the game expects the player to TalkToEveryone in town while waiting for the ItemCrafting NPC to finish, but the actual programming causes the EventFlag for them to finish to turn once the player leaves the building. This leads to the hilarious situation where the NPC can apparently finish the InfinityPlusOneSword in less than half a minute.

If the game forces the player to finish a dungeon or some other plot event before the "commission" (likely some PlotCoupon) is finished, that's a BrokenBridge.

* ''VideoGame/TheLegendOfZeldaPhantomHourglass'' has a convenient distraction in the form of a sub-plot resolution when the blacksmith is forging the Phantom Sword.
** ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'' did this as well with the Level 3 Sword. If you left the building and immediately returned, the smiths wouldn't be finished, but all you have to do to trigger the flag is leave the larger map screen where the shop was located. A faster way is to get there in the Dark World, whip out the mirror, go to the Light World, drop the thing off, then step in your mirror portal and immediately warp back. All done!
** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' does this with the Biggoron Sword. It takes four or five days for him to finish making the sword, after you run through the mother of all fetch quests. In this case, it can be accelerated through use of the sun's song.

* The Healer in the VGA remake of ''QuestForGloryI'' does this when making the Dispel Potion. In the original EGA version, however, the healer actually ''does'' take an in-game day to make the potion for you, as does Salim in ''QuestForGloryIII''.

* In ''VideoGame/{{Diablo}} 2'', Act 3, Alkor the alchemist tells you to busy yourself while he's experimenting with the ashes of Ku'yleh, but clicking on him again is more than enough.

* A variant in ''VideoGame/WorldOfWarcraft'' is equally silly. You're told to wait, but three seconds later he's done. However, there's a good reason it doesn't happen for more than a few seconds in [=WoW=]. Griefers could simply log off and wait in the building to prevent anyone from turning in quests to that NPC.
* Quite a few contacts in ''VideoGame/CityOfHeroes'' have dialog that reflects passage of time in between missions in a story arc, even if you select the next mission right on the heels of the last. "I'll have this mysterious substance analyzed to find out what it is. Good, you're back. I had that stuff analyzed and..."

* ''VideoGame/{{Final Fantasy IV}}'' has one of these when a blacksmith is forging you a weapon. The flag triggers as soon as you go to the moon.
** Attempting to breed chocobos in ''VideoGame/FinalFantasyVII'' involves "wait time." The flag is triggered once you fight about ten battles at any spot.
** In ''VideoGame/FinalFantasyVIII'', after finishing the first half of the Shumi Village sidequest (when Attendant is assigned to help sculpt Laguna's statue), the quest will not continue until you exit to the world map and re-enter the village.
* The fossil reviver in all the ''Franchise/{{Pokemon}}'' games. Sometimes you actually ''do'' need to walk around a bit, but it's just as common that you can walk out and into the building.
** Averted in the Day Care Center, where you must spend some time walking to get [[HotSkittyOnWailordAction two paired-up Pokemon]] to yield an egg.
** Also averted with the Apricorns in the Generation II games--after giving the Apricorns to Kurt, you have to wait a day before coming back to retrieve the special Poke Balls made from them.
* The blacksmith in ''VideoGame/GoldenSun: The Lost Age''. In this case, you also have to leave the entire village.
** Instead of leaving the town, you could also just spend the night at the inn or walk into the sanctum.
* The end trigger in the 'Mission's Brother' quest in ''KnightsOfTheOldRepublic'' is a particularly amusing example: the trigger for the next conversation is you leaving the zone, but because of how the despawning system works, you can overtake Griff on the way to the door, come back in and be told he skipped town while he's still visible behind you.
** If you ask Ajuur to set up a duel with Bendak, it "takes some time" to bribe officials etc. If you have that conversation late enough in the main Taris storyline, this is apparently just long enough for you to get to the door and back.
* In ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'', the Hammerhead Bros. say this to Mario and Luigi before they make hammers from the Hoohoo Block that fell into their workshop.
** As well as when the [[BrokenBridge bridge]] is being repaired so you can get said block. Thought somewhat of an aversion as you actually have to TalkToEveryone before the event flag will trigger.
* Common in the ''Franchise/TalesSeries''. Whenever it is ''not'' used, it's usually to cram in a cutscene or another dungeon for you to loot while it's being made.
* In ''VideoGame/TheElderScrollsIIIMorrowind'' you do need to wait for several days for the statue you ordered to finish the construction, but you need to exit the building if you try the rest method, or else the sculptor won't go make it.
** Being a game that is aware of its own internal calendar, and likes to use it, ''VideoGame/TheElderScrollsIIDaggerfall'' has the player submit his worn weaponry to a merchant who has skill repairing weapon items and being asked to come back in x days when it's done. In fact, it takes x+1 game days to be repaired as the merchant doesn't even start on it until the next day.
* ''VideoGame/NeverwinterNights'' is ''all over'' this trope.
* ''VideoGame/UltimaUnderworld'' features a blacksmith character who will repair your items. The trope is averted by requiring X ''real time'' minutes to accomplish the repairs, although you can skip this time by sleeping.
* ''VideoGame/TheWitcher'' also uses it sometimes; in at least one quest, when Geralt is supposed to talk to an NPC the following day, it suffices to change location (for instance, enter and quit a building). It happens ''two more times'' during just that one quest.
** A few such occurrences have the NPC completing the task just by ''re-initiating conversation with them after they told Geralt to wait''.
* At one point in ''VideoGame/{{Dubloon}}'', [[TheCaptain Timber]] has to built another ship while on Pyrite Island. It takes as long as you re-enter part of the island where he is.
* Averted in ''VideoGame/{{Persona 2}}'' with the sweepstakes magazines. After handing them over to the friendly NPC who will fill them out and mail them in for you, you have to go kill some time in a dungeon before any prizes will arrive.
** Also in ''VideoGame/{{Persona 3}}'' because the game follows a strict calendar time outside the dungeon, where each day is divided into time periods that some actions will advance. The antique shop owner always requires a day (or two, for everyone's ultimate weapons) to produce requested weapons.
** And in ''VideoGame/ShinMegamiTenseiStrangeJourney''. There's a dwarf in one area who will make you special weapons if you bring him the right forma, but it takes him a set number of [[WeirdMoon moon phases]] to finish.
* The builder in the Westguard in ''{{Spellforce}} 2'' will often tell you to "go save someone" while he finishes some improvement to the province's castle. This pretty much means to leave the map and come back.

* In some of the ''Franchise/HarvestMoon'' games, you'll be kicked outside while your wife is delivering your child (obviously not in those games where [[DistaffCounterpart you're playing a female farmer]], since she's doing the delivery herself, though her husband may still be told to leave). Whether you can reenter right away or not varies by game; in some, reentering your house will kick the clock to evening, and in others, you must wait around on your farm until after a certain point in the afternoon or evening (this gives you a chance to work, though usually with the caveat that you can't leave your farm itself, so no gathering in the mountains or talking to other villagers).

* When you give Naomi the Military Secret or [[spoiler:Japanese Sword]] in ''VideoGame/NoMoreHeroes'', she tells you to come back later for a new beam katana. "Later", of course, means "as long as it takes to leave and come back in"... though they're so expensive it's more like "leave, do a few assassination side-jobs, come back in".

* ''ShiningForce II'' has this with the {{mithril}} weapons.

* A solid example appears in the game ''VideoGame/{{Prototype}}'', where the resident Doc has to analyze a bunch of genetic material and come up with a functional cure to a weaponized cancer designed specifically to kill Alex Mercer, who is infected with a strain of virus which is ''also'' a weaponized super-disease. The man does it in as long as it takes you to walk back into his under-equipped morgue.
