One of the things I like about WoW is that its system requirements are CONSIDERABLY lower than for EQ2 or even the original Everquest.
EQ and EQ2 are, IMHO, very poorly programmed. I'm not certain why they are even keeping "zones" in EQ2, you would think they would be able to work past the need for this. Five years ago when EQ came out it was fine, now it's just being lazy.
