What is your opinion about Heroes IV?

Yes, especially since the same world was used in Heroes III and Heroes IV. And NWC and 3DO came up with the perfect plot: the world began to crumble (what kind of nonsense is that?), and everyone was saved by fleeing in disgrace. And after that, they created SOMETHING that caused the world to immediately collapse, and the prophet-UBISOFT arrived and created a new world.
In Heroes III, is the Hydra a sausage like in Heroes IV?
In Heroes III, is the Minotaur a naked brute like in Heroes IV?
In Heroes III, are the Nagas Japanese with swords?

Compare the heroes: take Ajit (a Chaos hero), for example. In Heroes III, he was a lord, but in Heroes IV, he's a thief?! Ivor is a monk, and in Heroes IV, he's a priest (a lower status). And how can Heroes IV be considered a continuation of the series?
BUT: If Heroes IV had been released under a different name, it would have been more successful, IMHO.

Why did the world begin to crumble?
Simply because Gelu obtained Armageddon's Blade.
And he was going to take the Ice Blade, but the Ancients knew that if the blades were combined, the world would be destroyed. So they sent Tarnum
to stop Gelu. He stopped him and captured the city where the Ice Blade was located, but the blade had already been stolen by Kilgor's wife and given to Kilgor. THEN the end of the world occurred, but portals to other worlds remained (probably those portals that needed to be activated in Might and Magic VII).
Ajit was a lord of the Underworld:mad:, and after the end of the world, he started accumulating wealth, which is why he became a thief:). And when he steals enough, he will become a lord of the Underworld again. And the second reason is that he is in the Castle of Chaos, and they don't create anything, they destroy. And if he were a lord, he would have to maintain order, which is a different race.
And I wrote about the monsters because you claimed that they are identical (in Heroes III and Heroes V):mad:.
And I didn't say that the monsters in Heroes III and Heroes IV are similar:mad: :mad: :mad: :mad: :mad:. The Minotaur in Heroes IV is better than in Heroes V:cool:. The Hydra is not a sausage in Heroes IV, but in Heroes V:rolleyes: :rolleyes:.
The Naga is normal!!!:mad: :mad: :mad: :mad:
