How many factions are there?

Is the more races, the better? How many is that? 25, 35, or maybe 50? That would be totally cool! But then you'd have to come up with and create new Campaigns accordingly. And that's a huge amount of work! I think having too many races is a Dragon Utopia. As of today, there are 8 races in the game: 3 good, 3 evil, and 2 neutral. I think the best option would be to introduce 1 more neutral race. Let them be the Swamp Creatures (like in the 3rd part). I feel like they are damn well missed!
