What is your opinion about Heroes IV?

It's strange that my on-topic response, addressed to Sage, was deleted by the moderators, but I won't repeat myself; I'll just say that after all the patches for the fourth game, it's unlikely that it has any clearly weak points left, and the claim that it's "falling behind" compared to the third game is a very debatable statement. If it's so different, then why are you comparing it?
