How many factions are there?

it's interesting, but don't go overboard; we need to remain realistic. You can't create too many races, no matter how hard you try, and the game will become less original if ideas keep being transferred from one version of Heroes to another. For example, there are many ideas for new cities for In the Wake of Gods, but only a few are actually implemented; there won't even be ten. Although, a couple of new races wouldn't ruin the game.
