So … I kept promising a review of World of Warcraft: Wrath of the Lich King and after so much time here it is.
While for most of the Windows software you can find an alternative program that run natively in Linux, for the game market is not so easy especially since it is more prone to the need to run exactly that game title and not a similar game.
Many games software houses are starting to follow the lead of idSoftware in making the games cross platform, but unfortunately we are still far from having all the games ported to any (major at least) platforms.
So here it is my guide on how to install and run World of Warcraft on a Linux distribution.
One of the biggest limitation that most user have when they would like to migrate from Microsoft Windows to Linux is that some application they are too familiar with (and maybe have spent some money on to get the license) is available only for Windows. Fortunately there is Wine (http://www.winehq.org/) an Open Source (and free) implementation of the Windows API on top of X, OpenGL, and Unix.
