I don't know about WoW but i got EverQuest 2 there is way more stuff to do then any other MMO i playd more then just wack and slash xp sink hog,
Amazing Graphics for the future
(a bit slow on current hardware)
(solo,group,raid,ect , got some very nice instanced quest reduced mob campeing greatly )
Houseing and decorations
(own a house or apartament in different places not just inn , get stuff to decorate inside , have pets ect ect.)
( awesome game in itself , gather resource build from cheap to rare items) (Food/Clothing/Metal work/Wood work/Alchemy/Skill makeing ect)
(world interacts with itself , wolf hunting deer , dog chases cats ect to much to name , day and night changes in real time , night sky looks like real !!
, fog , rain ect ect).
Awesome character customization.
