Blizzard's success has been partly due to their targeting of the lowest end systems for their games. Supporting WinXP is not surprising thing. An example is when they launched the original Starcraft, they chose to go with sprite based graphics, at a time when realtime 3D had become the norm. This allowed them to not only produce a better looking game, but combined with the 640x480 screen resolution, run on many machines.
