World of Warcraft vs. EverQuest II

Game Industry News is offering up a feature-by-feature comparison of EverQuest II and World of Warcraft, giving EQ2 an overall score of 4/5 and WoW an overall score of 5/5. An excerpt about questing:
Both games are just chocked full of quests waiting to be completed. In EverQuest 2 you find them by talking to every NPC you come across and some give quests and some do not. Some are appropriate for your level and some are not and they are color coded to assist identify the ones you can tackle right away. Quests in EverQuest 2 are for the most part not repeatable.

World of Warcraft handles quests completely differently. NPCs may have exclamation points over their heads indicating there is a quest available from them. Yellow ones indicate they are appropriate for your level while grey ones indicate you should come back in a level or two and see if they are your level or not yet. An NPC with a yellow question mark over their heads indicates an NPC you need to talk to in order to advance one of your current quests. Again grey question marks indicate an NPC you are currently on a quest for but have not yet fulfilled what they need to advance your quest. Both games have a quest panel that keeps track of your quest activities.
