Legends of Norrath digital trading card game can be played completely separately from EverQuest, the two games have a lot of ties to each other beyond just lore. The former can be launched from within the latter game. There are also "loot cards" which not only function in LoN but can be redeemed in EverQuest for certain bonus items. Some people that play EQ but not LoN may have been upset in the past at missing out on a few of these loot card items, but it's doubtful that anything has caused as much of an outcry as is currently occurring over an upcoming loot card. The card in question is the Dragon Brood Crypt Key Card, and the resulting EQ reward will be the only way to access a brand new dungeon instance.
