* {{Altitis}}: Not initially, as leveling up was originally [[LevelGrinding really hard.]] Some time around 2007, Mythic made it '''much''' easier to level, so much that one can reach the LevelCap of 50 in a few days. As such, most players will have a ton of different characters.
* CutAndPasteEnvironments: All the "old world" (i.e before any expansion packs) dungeons use the same three or four tilesets, likely due to technical limitations at the time.
* GameBreaker: The convoker master level 9 spell "Summon mastery". Its a buff that make your pet WAY more powerful for about 6 minutes, allowing you to solo purple (read: you should have no chance of beating this guy solo) monsters.
* 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 stated they chose RuleOfCool by calling Ireland Hibernia and not Ériu or Éire.
* MemeticMutation: [[LootDrama "YOU]] [[ClusterFBomb FUCKING]] [[NinjaLooting STOLE]] [[RageBreakingPoint MY]] [[RareRandomDrop CLOUDSONG!"]]
* 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.
* SpiritualSuccessor:
** The game is one to the MMO ''Darkness Falls'' -- and the major [=PvP=] dungeon is named after it.
** 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 [[PlayerVersusPlayer 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.
* ThatOneLevel: Treibh Callaite in Hibernia. Mainly due to a ''very'' odd and confusing teleporter system. To wit: each teleporter has a (non aggressive) golem standing on it. To teleport you must kill the golem and then stand on the teleporter till it respawns about a minute later, [[MoonLogicPuzzle at which point you are teleported]]. To make things worse, each teleporter has two possible destinations, and if you are doing the quest to kill all the bosses you will need to go to both locations for both teleporters (which place you teleport to is random so you may have to try several times before you arrive at the right place.)
* TheyChangedItNowItSucks: The Trials of Atlantis expansion introduced master levels that had a host of repercussions in the [[PlayerVersusPlayer PvP]] side of things, some of which are so despised that there are "Classic"-flavoured servers.
