do not have to have the demo running to read the manuals or tutorials! Save your time for actual game play. This is the style of game package with community support that continuously keep game play fresh even if releases new releases don't show up. And the polite designers set the brightness bar at the lowest setting for comfort. Those of you who like blasting lights can increase the brightness even though the scenes are "perfect" at the default settings.
You have to see for your self - no review can do it justice. Get the demo - you can't lose.
