For the longest time, video games told stories only through dialog that would occur either during cutscenes, or when you walked up to a person and hit the button to talk to them.

But now, with the growing trend toward more cinematic and story-oriented games, companies are starting to have their characters talk and hold conversations during gameplay.

Naturally, this occurs in games where a group of characters travel together, since otherwise, there'd be no-one for the hero to talk to (though many games did have solo heroes making one-liners--or just [[ICantUseTheseThingsTogether chatting with themselves]]). Oftentimes, the heroes will be traveling the countryside, wandering through a town, or so on, and the characters will talk to each other. Or they might remark on something they just saw, or something that recently happened.

This tends to make the characters feel more "alive" by showing their personality, but it also has the benefit of conveying story and character without hurting the flow of gameplay. If [[{{Uncharted}} Nathan Drake]] quips with Elena and Chloe while you're making him explore a ruined city, then you don't have to stop what you're doing just to watch the characters talk. Plus, it gives more of a feel of actually being there with those characters, to hear them conversing while you're controlling the lead hero.

On the other hand, this kind of dialog is easy to miss while concentrating on the game, especially if [[SubtitlesAreSuperfluous there are no subtitles]] and there is action going on. So it's best limited to background detail, with actual game-critical information given in cutscenes.

On the technical side, including unobtrusive dialogue is handy to [[LullDestruction fill in the boring sequences of trekking across safe/already explored locations]]. For the same reason, it is sometimes used in conjunction with DynamicLoading. It is also very closely related to ExpositoryGameplayLimitation.

Note: If the gameplay stops for any reason for the characters to talk, that's not this trope. Therefore, the skits from the Namco ''Tales'' series don't count. Also, if it doesn't involve characters talking ''to'' each other and only involves the main character remarking on things out loud, it's not ''dialog''.

See also BossBanter, which is when bosses taunt the player during gameplay - not quite dialog (as there's no back-and-forth).

!Examples:

[[foldercontrol]]

[[folder:Action Adventure]]
* Several of the ''{{Spider-Man}}'' video games have Spiderman and the bad guys toss back and forth verbal barbs at each other. Sometimes townspeople will talk to Spidey or shout up at him while he's swinging around the city, and he'll talk back.
* In ''VideoGame/BatmanArkhamAsylum'' (and [[VideoGame/BatmanArkhamCity the sequel]]), Batman will converse with Oracle and Alfred to discuss objectives and such during gameplay.
* This was an innovation in ''MetalGearSolid4''; previously, whenever Otacon or your other VoiceWithAnInternetConnection wanted to talk to you, they'd have to interrupt the gameplay by pulling up the Codec menu to talk to you. In ''[=MGS4=]'', Otacon gives tips to you right in the middle of gameplay; this becomes vital if, for example, you get totally lost inside a collapsed building.
* ''Harry Potter and the Order of the Phoenix'' has Ron and Hermione talking in the background about plot related subjects at regular intervals while you walk from place to place.
* In ''VideoGame/DeadlyPremonition'', when you have passengers in your car, there's conversation between York and his passengers. York can also have one-way conversations with his invisible friend Zach when he's driving solo.
* ''VideoGame/InFamous'' has conversations with your companions when you're on an escort mission sometimes, and you regularly have Cole talking to various people on the phone during gameplay. One time Cole's jerk friend Zeke calls up in the middle of a battle, and won't take the hint that now is not the time to be talking about cool names for Cole's new superpowers.
* ''Franchise/AssassinsCreed'' occasionally has the voices of your support team appearing during gameplay, and regularly has dialogue during escort missions. Boss fights sometimes have the player character and the boss trading words.
* ''VideoGame/BeyondGoodAndEvil'' has protagonist Jade and her partner characters talking constantly with her. Some of it allows them to exercise their ExpositionFairy sides, but some of it is simply for flavor or character-building.
* ''VideoGame/GrandTheftAutoSanAndreas'' has this during some boss scenes. Thus, sometimes delaying the death blow so the player can hear what else the opponent has to say.
** VideoGame/GrandTheftAutoIV has the above, with the addition of conversations that take place while you are driving to missions. Almost every mission has a conversation, and there are even alternate conversations that occur if you have failed the mission and are attempting it for the second time. On the third pass, the [=NPCs=] usually just want to listen to the radio. The player can also make and receive phone calls during gameplay, and it's just as tricky to dial a mobile while driving as it is in real life.
* In ''VideoGame/ScarfaceTheWorldIsYours'', in the 'storage area' an extra summoned mook will sometimes decide to get into a verbal shouting match with the mook that shows up because it's a storage area.
* All conversations in ''VideoGame/DeadSpace'' and ''VideoGame/DeadSpace2'' happen in real time through the videologs projected from [[DiegeticInterface Isaac's RIG]]
* Happens while the player is platforming in ''Franchise/PrinceOfPersia: Sands of Time'' trilogy. Sometimes, the conversation is distracting and leads to the player's death, making them miss out the rest of the conversation.
** Likewise, there is a lot of banter between Prince and Elika in the [[VideoGame/PrinceOfPersia2008 2008 version]].
* All the dialogue between Faith and Merc in ''MirrorsEdge'' happens via Faith's headset while she is [[LeParkour running really fast]]. Apparently, she is just that good at keeping her breath steady.
* ''VideoGame/SilentHillShatteredMemories'' allows Harry and anyone currently travelling with him to hold a conversation en route to their destination, either on foot or in a vehicle.
* Naughty Dog title ''VideoGame/TheLastOfUs'' has not only story-related dialog, but also banter that occurs before, during and after fights. Even when a fight is not finished, Ellie might exclaim "Holy shit, Joel!" when Joel lights someone on fire with a molotov cocktail, and Joel will tell her not to freak.

[[folder:Arcade]]
* In the ''AceCombat'' series, most of the dialogue takes place while you are flying/dogfighting, though the really important (story-relevant or character-building) exchanges take place during the quiet getting-to-the-target-airspace sequences. In ''AceCombat5TheUnsungWar'', you could even participate in it with simple yes/no answers (if you didn't press a corresponding button due to being too busy actually playing, the prompt disappeared after a few seconds and the dialogue continued).
* This goes all the way back to ''VideoGame/SpaceAce'', with Dexter and Kimberly exchanging witty banter (and exposition) during action scenes.
[[/folder]]

[[folder:First Person Shooter]]
* The ''VideoGame/Left4Dead'' series has lots of this. Characters talk to each other frequently, mostly yelling out information (such as enemy positions), but sometimes hold brief conversations as well.
* Also shows up in copious amounts in ''VideoGame/BioShockInfinite'', which Booker and Elizabeth talking and exchanging banter even in the middle of a firefight.
[[/folder]]

[[folder:Hack and Slash]]
* Characters in HyruleWarriors keep up a running commentary of the battle, to inform you of their plans or to ask for your help when they're overwhelmed. Unlike most examples of this trope, the dialogue is not voice-acted (since it is a Zelda game) other than a short gasp or similar sound to alert you to their dialogue. Given the hectic nature of battles in the game, it can be quite easy to miss unless you happen to glance over at the bottom corner of the screen at the right moment.
[[/folder]]

[[folder:Platform]]
* ''SonicAndTheSecretRings'' has Sonic the Hedgehog accompanied by a fairy/light that follows him around, and sometimes the two talk to each other.
** The same happens in ''VideoGame/SonicHeroes'', where the team members talk among themselves during gameplay.
* Used in Meta Knight's Revenge in ''VideoGame/KirbySuperStar''. The villainous crew constantly banter among each other (even giving out gameplay/boss hints) while you play through the game.
[[/folder]]

[[folder:RPG]]
* BioWare's [=RPGs=] frequently have this, as part of the company's traditional attention to characters. The fandom's term for this is "PartyBanter", since most of the dialogue takes place between active party members.
** The ''Videogame/BaldursGate'' series started the tradition but there, the party members with opposing world views would start arguments and draw on the PC for arbitration, thus making it a regular cutscene. Sometimes, however, they would spontaneously compliment each other while traveling, playing this straight.
** The ''Franchise/MassEffect'' series follows suit, with squad members conversing behind Shepard's back, especially during the elevator rides used to conceal level loading in the first game.
** The ''Franchise/DragonAge'' series has a set of predetermined locations, passing through which would trigger dialogue between two (sometimes all three) [=NPCs=] accompanying the player. Each pair of characters has 5-6 dialogue bits that play out sequentially, regardless in what order you visit the trigger locations (though some play only after certain plot events), and each bit reveals hidden aspects of their personalities (like Leliana catching [[TheStoic Sten]] [[PetTheDog playing with a kitten]], or [[AnythingThatMoves Zevran]] hitting on [[IceQueen Morrigan]]). ''VideoGame/DragonAgeII'' even lets the SuddenlyVoiced PlayerCharacter participate in the banter.
* ''RogueGalaxy'' had a feature called "Active Chat" (a possible title) where as you run about each planet, the active members in your team quip random comments. Many of these were context-sensitive, reflecting on the current situation/objective, the previous RandomEncounter, the surrounding environment, how long the player has been running around (or standing still), how long it's been since they used a SavePoint, or so on.
* ''VideoGame/FinalFantasyXIII'' has this; when you're walking around, sometimes your party members will comment on stuff like the scenery in the corner of the screen.
* ''Franchise/{{Neopets}}'' browser RPG ''Neo Quest II'' has a few lines the characters can randomly utter during any move outside fights. Each character has their own lines.
* ''VideoGame/TheElderScrollsIVOblivion'' has [=NPCs=] getting into conversations about rumors and current events with each other, while the player is walking around.
* ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'' had conversations mid-battle, usually as the result of player action (i.e. using items, taking a lot of damage).
--> '''Marta:''' You're using too many Artes!
--> '''Emil:''' It's to win!
** This has become very common amongst many games in the ''Franchise/TalesOf'' series. Frequently, the beginning of a BossBattle will have dialogue between the participants during the fight itself. Party members may comment on the player's tactics, such as using the same technique repeatedly or running around the enemies and not attacking.
** ''VideoGame/TalesOfXillia'' and its sequel both have your party members provide dialogue while you're moving about in the field.
* Your party members in {{Persona 3}} and {{Persona 4}} are quite chatty during battle, and they provide all sorts of commentary on things like scoring a critical hit, missing an attack, finishing off an enemy, another party member finishing off an enemy, getting inflicted with a status element, an ally getting downed, number of enemies left, etc, etc.
* ''FossilFighters'' includes {{Combat Commentator}}s discussing the battles going on, via text boxes on the DS's top screen. Like with ''VideoGame/KirbySuperStar'', you can pick up tips if you pay attention.
* Almost all of the storytelling in ''VideoGame/{{Sonny}}'' is done via this, since the game is essentially a long string of battles with only a single fairly short cutscene in between each chapter.
* ''TheLastStory'' does this almost constantly throughout the game. there are even many sections where a player might hold back in finishing off a boss in order to hear the full conversation.
[[/folder]]

[[folder:Third Person Shooter]]
* The ''{{Uncharted}}'' series lives and breathes this trope. There's a lot of conversations the characters have with each other during gameplay, not just during exploration but also sometimes even during battle!
* There's lots of chatter with your wingmen in the ''VideoGame/StarFox'' series. Sometimes enemies exchange taunts with the heroes, and sometimes other characters talk to the Star Fox team. This has been happening since the first game, which originally used only text and no voice acting to convey the dialog.
* ''VideoGame/KidIcarusUprising'' has a lot of this during both gameplay types - the flying and the on-ground fighting. Pit has a lot of back-and-forth dialog with Palutena, and other characters, such as bosses, have a lot to say during gameplay as well. Some of it is story-related, while a lot of it is comedic banter.
* ''VideoGame/LANoire'' likes to include dialogue while you are driving to somewhere. If the player has his partner drive, which automates the trip, the conversation will complete before the cut to the destination.
* Ditto ''VideoGame/MafiaTheCityOfLostHeaven''.
* Walker, Lugo and Adams frequently converse during ''VideoGame/SpecOpsTheLine'''s campaign.
