Pros:
Diablo is straight from the bonds of Hell with evil powers to possess the inner realms of your multimedia platform. Highest quality sounds, icons, are cursors are only the beginning of the Diablo experience. The wallpaper alone is enough to terrify the weak. The sound files have been updated to a newer sound compression format for even better stereo sound quality in a smaller file size. --- This update makes installation easier with a self-extracting archive.

Cons:
This is definitely not a theme for those who are young or religious. It has a devil worshiper look and sound about it. Speaking of sound, startup and shutdown sounds are a little too long for a desktop theme. Lets just hope you don't have to restart windows often. You will be waiting for eternity..................

Overall:
As long as you don't start drifting into dreams of fire and brimstone, this theme should be around for those moments like Halloween and aunt Betty's birthday. A few more (short) sounds and this would get another star.
