What is your opinion about Heroes IV?

Heroes 4 is a dead end in the series...

Heroes 4 isn't a dead end in the series. Heroes 4 was once a continuation of the series, now it's more of an intermediate link. My point is, one game in the series can't be a dead end. So, there's no need to criticize it just for the sake of it. If you don't like something, write about it in the appropriate thread.
