Alt-itis: 3 races, several classes within said races, dozens of versions/game servers.
Broken Base : With the myriad of private servers and official servers, players have different views on which is the best and most fun to play. They're also scattered across all these versions.
Especially common on a certain forum, terms like Job Change (JC) to refer to the Advanced Class/ Promotion of players above the level 150 mostly due to a bad translation on a Chinese server of the characters for "job" and the idea of "change" as in a promotion.
Another term was to refer to the boss found in Adam N as Adam while others used Adam's Keeper whereas his official name is the Great Ruffian.
Rare skill books were also referred to as null or null strings because the name of the skill was missing and only <null string> would appear in game.
Fridge Logic : The game provides plenty examples, for instance one can wonder how come such an advanced military unit such as E.V.E can not provide some simple night vision helmets to their slayers so they could see in the damn darkness.
Play the Game, Skip the Story: Very few players actually know the game's story, actually some don't even know that Tepes is Dracula and call him by the game's typo "Tepez".
