It's a pay-per-month thing, but if you buy the longer times, it's cheaper. It's the same as World of Warcraft, 15$ a month/9L$/13E$. You get 30 days free for buying, as is usually the deal, plus a 7-day guest pass to give to a friend. Be warned, though, it taked up 32gb on your hard drive (or that's how much it asked me for), and you need a fairly recent computer to have most of the eye candy on.
