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

"The Restoration of Erathia" was my first... I didn't pay attention to the plot; I was too busy... I didn't really play parts 2 and 4. I explored "Armageddon's Blade," "The Shadow of Death" (except for the last campaign), and part 5 with the expansion. However, I'll still choose "Armageddon's Blade" and its campaign. Look how fresh and innovative the plot is – there's Roland, who returned from captivity, a new artifact, a new city, a new hero, Krieghan, and much more.
