LOTRO: Mines of Moria Pre-order

i have found this page

http://www.offgamers.com

in which you can pre-order the game LOTRO: Mines of Moria Pre-order and they will mail you a retail cd key but no cd or dvd, my question before ordering its, if i receive a retail key..and i don't have the physical device.(cd dvd) will the client update with the content or no?…i have a big mess in my head about pre-orders and stuff with all the things that have been written in the forums…

please i need an answer

for MMOs (like LOTRO) all you really need to install anything is the client loader, a very small program that connects to the internet and downloads whatever you don't already have in your computer. The loader will download what you need once you add your key to your registration.
