My favorite game in the series. Although the third installment will always hold a special place in my heart, and playing it with my father is one of my fondest childhood memories, after the release of the fourth game, I simply stopped playing Heroes 3 and never went back. I've spent hundreds of hours playing Heroes IV. I tried the fifth game, but it didn't quite click with me.
I wouldn't say that Heroes IV was a revolution. It was more of a bold attempt that, unfortunately for its fans, didn't achieve widespread success, but it deserves respect for its daring decisions and radical innovations.
