Just to let you know just in case that you want to buy the "Eye of the north" expansion. It is the true expansion, nightfall & the others are just different campaigns. Eye of the north requires you to have at least one character to be lvl 10-20 to play. (it used to be just lvl 20 at first when it came out couple months ago, but they changed it because most ppl didn't know that you had to be lvl 20) Also you cannot access it right away. You have to get further into the game to access eye of the north. Hint Hint: Lion's Arch.
