[[caption-width-right:182:Famous parties in Nintendo platform history.[[note]]From top to bottom: ''VideoGame/FinalFantasyI'', ''VideoGame/FinalFantasyIV'', ''VideoGame/{{Earthbound}}'', ''VideoGame/SuperMarioRPG'', ''VideoGame/ChronoTrigger'', ''VideoGame/{{Mother 3}}''[[/note]]]]

[[TabletopGames Tabletop]] and VideoGame {{RPG}}s, as well as certain other games, feature not one but several {{Player Character}}s, banded together in {{Ensembles}} of 3 or more, fighting evil together. Such an ensemble is known as a "party". Unless the player wants to beat the game using a [[SelfImposedChallenge handicapped group]], most selections comprise most if not all of the available choices inside the entire party.

In tabletop [=RPGs=], {{MMORPG}}s, and other multiplayer games, each PC is usually controlled by a human. In singleplayer games, the player usually controls [[ManualLeaderAIParty a leader PC while the computer steers the rest of the party]]. Additionally, the player is often given the option to micromanage each party member, particularly in combat.

In {{Role Playing Game}}s where the characters are pre-plotted (in comparison to, say, ''VideoGame/FinalFantasyI''), the Party is usually a specific variety of Ensemble, such as the PowerTrio, FourTemperamentEnsemble or FiveManBand. Furthermore, the party members' tendencies to stick together for the length of the game (temporary members notwithstanding) mean that they are usually written as TrueCompanions.

The concept of [[AnAdventurerIsYou Character Classes]] is usually dependant on characters being in parties. The SquishyWizard and the MightyGlacier tend to counter each others' weaknesses perfectly, so it's expected that one assists the other throughout the game.

In a group of Tabletop Roleplaying, the chances of all group members picking the same class are extremely low. This is partly because everyone wants to play a [[SpecialSnowflakeSyndrome unique character]] and also partly because people like to help and complement other people naturally as part of a functional cooperative unit. If a member voices his desire to play a MightyGlacier, the chances someone else will play one are usually low.
