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

I really like the campaigns in the 4th game. Especially "The Gathering Storm". I haven't played the 2nd and 3rd ones much, so I can't really evaluate them:smile43: In the 5th game, the plot is interesting in my opinion, but I like the 4th one because you can do so much with a hero without an army...:rolleyes:
