Black and White, was one of Molyneux games.
You played a god or a divine hand, who was sent to earth to help a small village, you are given a creature that you control, that helps you serve the village, to gain more followers,or you could take the war route and simply destroy any one in your way, both will allow you to progress trough the game...
One of the main selling points was you could ether be a good god, or a evil god, both could get you followers and make you progress, your creature will allso ether become good or bad, and it will change its appearance as you progress ether becoming more evil, and hurting the citizens, or good and help them.
In a nutshell
Black and white 2 > Spore
Think Civilizations, a evolving spore like creature you semi-controle, and mixed with the Good/Bad engine from fable.
