World of Warcraft! what do you think?

Never really played it, but i've seen people play it and it's pretty intense and also really big. There are like five expansions to it with two more planned for the future. I don't actually know a lot about it except that you need a really good graphics card in order to make the game look good. Otherwise you only see like half of your character because the graphics are so high. Also their are like 3 million+ players and a lot of people play it from nerds to jocks. So what do you think??
