How many factions are there?

In my opinion, Hammers of Fate is already a good game in terms of quality. Perhaps Tribes of the East will improve it a bit, but if they continue, they should start working on the 6th installment. And please, make the heroes separate entities so they can be easily removed (like in the 4th game).
As for increasing the number of factions, we can say, "They wanted to make it better, but it turned out as always..."

And finally:
It was bad, and now it's even worse. Make it just bad again!
