What is your opinion about Heroes IV?

Clever Ann, you're absolutely right—4 is a decent game (especially for those for whom it became their first serious game), but it is NOT HEROES; it's a separate standalone game. IMHO, if it had been called something else and released by someone else, it wouldn't have reached such sales, but it would have received higher reviews and more fans.

And nobody mentioned any comparison

In my opinion, all you see there are screams like "why the hell did anyone vote for 5", "all the castles there are worse than just one here".........

P.S. And one small thing..... When I first started playing 4, I could understand the centaurs in the Barbarian castle (fine, they serve someone else in every part anyway), but as for the orcs with Chaos (along with the black dragons), I would've killed them for that........ It's so simple: just swap the models and historical justice is restored.....
