Query: World of Warcraft is great but tough to install.

A fantastic game - easily played and graphically beautiful. Patience will be needed during the install as it does not actually install from the box as it is supposed to. Patches are available on the website and tech help is 12-48 hours of lagtime. That said, I am playing it and having fun, but on the free trial version as I have not yet figured out how to get the full install completed and this is a week after receipt of box.
