Which installment of the Heroes series had the best campaign storyline for you?

of course, Heroes 3!
There, heroes transitioned from one part to another (for example, Jelu, he was in both The Shadow of Death and Armageddon's Blade), and in general, the characters were the best in part 3... and the campaigns were interesting too!))

And in part 4, each campaign (The Gathering Storm, Winds of War) has new heroes...
