I play WoW, and have since closed beta. We went to Fry's the night before release and stood in line for 6 hours to buy our copies. My husband got a regular edition game (4 cd's), whereas I got the Collector's Edition (1 dvd and several collector's items), which I then had signed by almost all the developers. It was great fun.
As for the game itself, I would recommend it to anyone as I've made many friendships in the game. I was playing in a very hardcore raiding guild up until about 2 months ago when I started being really fatigued from my pregnancy. I still play, but on another server with my husband. I recently got my brother back into the game. ^_^
All in all, it's worth it. And if you want to download patches fast, get a Fileplanet account (www.fileplanet.com). I have one and on patch day I downloaded the patch in 15 minutes.
