I didnt preorder it, I probably will go out and buy the game the day of release, like I did the original game. I am sort of scared that I will be forced to clear some items on my HD to make room for the game lol. I know if you have the game already, they have been implementing content through patches for several weeks now but its still got me scared of the size of the game.
Other than that its going to be great, although I am getting a little burnt out, once you have T2 armor, and a small portion of T3, the game becomes a little boring. But I guess that comes with the territory with MMO's.
