 value of playing a game more than once. In some cases, factors that influence replay value are the result of the game's programming (extra characters, alternate endings, etc.). Other times, the replay value of a game might be based entirely on the individual's tastes; a player might enjoy a game because he/she likes the music or graphics, finds the game play entertaining, or (in the case of licensed products) because of loyalty to the product line.

, a wide variety of ways to accomplish tasks, and a rich array of assets will keep a player coming back for more.

Plot

A game with a linear plot will typically have a lower replay value due to the limited choices a character can make. Games that offer more choices in regard to what the player can do, such as strategy game

s or construction and management sims, tend to have higher replay value since the player might be able to make each play through different. In the case of role playing games, plots can be linear or non-linear. The plots of older RPGs tended to show little to no plot changes with each play through. A good example of an RPG with a linear plot is Mass Effect

. Role playing games released in later years allow for more freedom. For instance, choosing to be evil instead of good might prevent certain events from taking place (or even cause new ones to occur). Likewise, allowing a particular character into the party could cause the plot to branch off in a new direction, if even for a short time. A good example of this point is the character Juhani
Juhani
Juhani is a common Finnish male given name and Arabic surname.-Given name:* Juhani Aho* Juhani Lahtinen* Juhani Aaltonen* Juhani Pallasmaa* Juhani Komulainen* Juhani Suutarinen* Juhani Kaskeala* Juhani Peltonen* Juhani Tamminen* Juhani Wahlsten...

 in Star Wars: Knights of the Old Republic. The player has the option of killing her or sparing her life. Should the player be merciful, Juhani joins the player's party. Later in the game, the player will then run into an enemy from her past.

Multiple classes

This is the ability to play as different characters each time through the game. For example, the game Diablo allows the player to choose one of three character classes: warrior, rogue, or sorcerer. Party-based RPGs can have a good degree of replayability, even if the plot is essentially linear. The plot of the first Final Fantasy game remained the same with each play through, but since the player was able to choose his party of four from six different classes he could choose a new party configuration with each new game. The Final Fantasy instruction manual even gave the player ideas for different types of parties (well-balanced, heavy magic use, combat oriented characters, etc.). In the first Final Fantasy game you can choose from the classes of Fighter, Thief, White Mage, Black Mage, Black Belt, and Red Mage, revising you with 15 possible character combinations with 4 distinct classes, or 126 with repetition.

Note that the characters change class as you progress:
Fighter-Knight; Thief-Ninja; Red Mage-Red Wizard; White Mage-White Wizard; Black Mage-Black Wizard; Black Belt-Master.

Multitude of classes, accompanied by a multitude of races, is another typical characteristic of roguelike games

at this moment employs 22 races and 23 classes, allowing a total of 654 race/class combinations (although about a dozen of them are disallowed due to in-game race/religion constraints). Typically, some races are more suited for some classes, and much less suited towards others (typically, an ogre usually makes a great fighter, but a very lousy wizard). Such "unsuited" combinations may prove an extra challenge for an experienced player, yet it's not frequent for this challenge to be high to the point of the game being unwinnable.

Multiple characters

In some RPGs, such as Skies of Arcadia
Skies of Arcadia
Skies of Arcadia, released in Japan as , is a console role-playing game developed by Overworks for the Dreamcast and published by Sega in 2000.

, the player controls the leader of a party of characters, and additional members will join the group if the player makes the right decisions. It is unlikely that a player will "collect" every possible member on their first attempt, so they may choose to play through the story again in order to acquire the full cast. Different characters offer new ways to tackle the obstacles within the game. In the case of action-oriented games, there may be some areas in the game that are only reachable using a character with certain abilities. For example, see the Sega game Sonic & Knuckles
Sonic & Knuckles
Sonic & Knuckles is a 1994 platform video game in the Sonic the Hedgehog series for the Sega Mega Drive/Genesis. It was developed in the United States at Sega Technical Institute by members of Sonic Team, and was published by Sega worldwide on October 18, 1994.As well as working as a standalone...

that the previous characters couldn't.

Some games might offer a wide array of characters from whom to choose to play with, but gamers are usually deterred from replaying if all characters share the same story line and function more or less the same. This is the case of Mercenaries: Playground of Destruction

and its sequel: the player can choose one out of three mercenaries to play with, but the story line remains the same, and the differences in gameplay (speed, strength and stealth) are too subtle to invite further replays.

Alternate paths

Some games give the player a choice of which path they want to take through the game. Two good examples are Castlevania III and Shadow the Hedgehog (video game)
Shadow the Hedgehog (video game)
Shadow the Hedgehog is a 2005 video game developed by Sega Studio USA, the former United States division of Sega's Sonic Team.

In Shadow the Hedgehog, Shadow must choose to do Neutral (self-work), Dark (evil work) or Hero (Heroic Work) in a stage (i.e. choosing whether to kill all the humans in Dark, kill all the black aliens in Hero or to grab the Chaos Emerald for himself in Neutral), and depending on what Shadow does, this will affect the next stage played and the storyline. There are 10 endings in the game that range from Shadow destroying Earth

- and occasionally crossing paths with the other character. Scenarios would differ by balancing odds and obstacles - an action-oriented scenario for the strong, male protagonist and a more puzzle-oriented scenario for the comparatively weaker, but faster female protagonist. Beating each scenario was required to get 100% completion, as well as all aspects of the story.

Unlockable characters and content

Sometimes beating the game or completing certain challenges will allow the player to use an NPC from the game or even a new character. For instance, in Baldur's Gate Dark Alliance, the drow ranger Drizzt Do'Urden

feature many different unlockables of this nature. As the player progresses through the game, he can view production stills from the movies, concept art, and interviews with some of the actors. Completing either game unlocks new characters, missions, and cheat codes.

Many games enhance replayability by unlocking a second, minor story mode once the main game's beaten. This second story or sub-scenario usually functions on the same game physics/mechanics and is set in an already explored area, and its main function is to expand on the main game's story and its unanswered questions, often focusing on a secondary character now turned protagonist, and his/her point of view.

features the 'Born From a Wish' scenario, chronicling events prior to the game's main scenario through the eyes of key character Maria.

Resident Evil 4 is a good example of large quantities of unlockables, ranging from mini-games to new weaponry, alternate costumes and other features. Beating the game in 'Easy' or 'Normal' mode unlocks three mini-games, a movie browser, two new weapons ('Matilda' and the 'Infinite Rocket Launcher') and a new difficulty level, 'Professional'. Beating the game in 'Professional' mode, in turn, unlocks the 'P.R.L. 420' weapon. There's also bonus content for beating each mini-game: beating The Mercenaries scenario with all four players with a 5-star ranking each unlocks the 'Handcannon', beating the Separate Ways scenario unlocks further alternate costumes, as well as the 'Chicago Typewriter', a weapon of infinite ammo, high-powered and needing zero reloading time. All unlockables affect regular gameplay, though beating the Assignment Ada scenario unlocks the Chicago Typewriter for the Separate Ways mini-game.

Alternate endings

One of the most common ways to increase the replay value of a game is to offer multiple endings. These endings are often based on the choices the player makes during the game, like choosing to be good or evil. Several games based on the Star Wars series make use of alternate endings, such as Knights of the Old Republic
Star Wars: Knights of the Old Republic
Star Wars: Knights of the Old Republic is a role-playing video game developed by BioWare and published by LucasArts.

). After completing the game, Uatu the Watcher will give a glimpse into the future and tell the player what the consequences of his or her actions are.

Of note is how the Knights of the Old Republic games make use of several of these factors to increase replay value. In the first Knights of the Old Republic game, the player chooses one of three classes: soldier, scout, or scoundrel. Later in the game the player chooses one of the three Jedi classes (Guardian, Sentinal, or Counselor). Thus, the player has nine possible character combination choices. In Knights II, the player starts as one of these three Jedi classes and gets to choose a prestige class. Additionally, the player gains different followers depending on whether he selects to be male or female and Light Side or Dark Side. Both games allow the player to customize his characters by selecting various skills and feats. Thus, a player might choose to focus on two-weapon fighting for one play through and single-weapon fighting in the next.

Oftentimes, a game will force a specific ending on the first play through, upon which new alternate endings will unlock during a replay, should the player meet certain requirements, perform certain tasks or obtain certain objects. Silent Hill 2 alone features a total of six possible endings - three regular endings, which can be obtained after the first play-through, as well as a bonus ending following a replay, and two unlockable "joke endings". Almost all games feature a joke "UFO ending", wherepun UFOs descend from the sky in an unlikely turn of events. Because there is little narrative continuity between the games, there are no canonical endings, except those of Silent Hill: Origins and the original Silent Hill

Other factors

Games where the map and starting position is different every time you play it, in for example strategy games with a random map generator, also tend to have long-lasting appeal. The community-developed mods for many games also contribute to increased replayability and long life for many games. Due to the limits of AI behavior and the appeal and challenge in playing against friends, multiplayer is also often considered to increase the lifespan of a game. For example, Worms Armageddon
