How many factions are there?

I'm in favor of having many races (a dozen would be quite enough; otherwise, it will be like in Heroes 3, where they couldn't come up with even 9 different races, or like in Dominion 3). But they should be different in appearance and gameplay (not like in Heroes 3, where one race is just in different skins). And there shouldn't be purely evil or purely good races, but neutral ones. There is no good or evil in general; everyone is driven by EGOISM. For example, they protect the world from demons, why? So that it will be easier for themselves. They save a person, why? So that they won't suffer later. They destroy everything, why? Because they like it, and so on.
