How many factions are there?

Simply brilliantly said!))) We're playing it now, and it's not getting boring. If they add a new faction, it will literally get boring within a month!)))

And there's no need to nitpick the words. It's not the game as a whole that will get boring, but the new factions. Or, to put it more clearly... they will become tiresome. Like the current humans, elves, etc.
