Launched in late 2001, ''Dark Age of Camelot'' is a long-running {{MMORPG}} from Mythic Entertainment.

The game presents three realms: Albion, a typical TheDungAges representation of medieval England which is heavily steeped in Arthurian myth; Midgard, a frosty, fjord-y representation of Norse mythology populated by Vikings and trolls; and Hibernia, built on Irish folklore and legend.

The three realms war in PlayerVersusPlayer frontier areas, while each realm's home territory is dedicated to Player Versus Environment play.

!!Dark Age of Camelot provides examples of:

* AllTrollsAreDifferent:
* AllYourBaseAreBelongToUs: This trope tends to get invoked when one realm's keeps and towers are taken away by the enemy realms. Reclaiming them largely depends on the morale of the realm's population, and losing all of them can be detrimental to many players' willingness to go out there. Since this is a three-way war, whose keeps are taken changes repeatedly.
* CastFromHitPoints: The "Savage" class.
* ClusterFBomb: Particularly from [[http://www.youtube.com/watch?v=Opl77bP7vbY&feature=related one player]] (video NSFW) who felt he was [[MemeticMutation wrongly deprived of his Cloudsong]].
* CriticalEncumbranceFailure: Subverted slightly. As you get closer to your encumbrance capacity, you begin to move slower. Once you go past it however, you're unable to move until you lighten your load a little.
* CriticalExistenceFailure: Played straight for the most part. As your health goes down, your character's movement slows down.
* TheDungAges
* DynamicDifficulty: The instanced dungeon difficulty is largely based on how many players are in the group, and it scales up or down as players join or leave.
** Levelscaling: it's also based onte player's level to an extent.
* ForeverWar: Pretty much the entire point of PvP in this game.
* GeniusBonus: Naming England Albion after it's oldest known name is quite clever. Midgard was the name of Earth in Myth/NorseMythology and considering Vikings originated in Scandinavia so it fits. However the game creators did commit CriticalResearchFailure by calling Ireland Hibernia and not Ériu or Éire.
* {{Gotterdammerung}}: Albion's time of strife after the death of Arthur.
* InnocentlyInsensitive: A meta example: Earlier in the game there was a pooka (basically an evil black horse) named Spook. Presumably his name was meant to mean a ghost however someone pointed out that spook is also an obscure slur for a black person so the creature's name was changed.
* InventoryManagementPuzzle: Good luck agonizing over which awesome loot to leave behind so you can stagger back to town!
* IstanbulNotConstantinople: The Realms of Albion, Midgard, and Hibernia are Fantasy names of England, Scandinavia, and Ireland respectively .
* LastStand: Players defending a keep lord as the room is being breached often experience this. Sometimes they hold off the attack, other times it doesn't go very well for them.
* KeystoneArmy: The Bonedancer class can summon up to 4 pets to aid them in combat...who all die instantly if the bonedancer dies. Averted by the Animist class in hibernia, whose turrets can stick around for a minute or two after the character's death.
* KingArthur: Albion's background mythology ''is'' the Arthurian cycle, and the titular "Dark Age" your character inhabits is the period after Arthur's death at Mordred's hands.
* {{Mithril}}
* ObviousBeta: The Hibernia realm was notoriously unfinished at the time of the game's release. Some of the dungeons weren't even open, most notably the Coruscating Mines. It took about a year and a half before all of the dungeons were opened and populated.
* PlayerVersusPlayer: Called Realm vs Realm in the context of [=DAoC=], but very much the opposite of PlayerVersusEnvironment.
* SpiritualSuccessor: The developer went on to do ''VideoGame/WarhammerOnline'', and most ''[=DAoC=]'' veterans instantly felt right at home.
** There's also a reboot called [[http://camelotunchained.com Camelot Unchained]] currently in the works.
** Additionally, ''VideoGame/TheElderScrollsOnline'' has three-faction PvP that is easily comparable in general setup to the Realm vs Realm combat. This is especially the case since some of that game's talent developed this game. The [[PlayerVersusEnvironment PvE]] experience is different, with standards in questing inspired by World of Warcraft.
* ZergRush: The classic Albion attack, although the other two realms use this tactic regularly as well.
