I don't understand why you consider Heroes 4 to be an "unsuccessful experiment"?
If that were the case, people from different countries wouldn't be playing this version of the game. And the Equilibris modding team wouldn't be working on the game.
I agree that the game was released in an "unsuccessful" – or rather, unfinished – state. Otherwise, Heroes 4 is an interesting game. It's quite difficult to learn how to play it at a decent level, but those who achieve this will find the game enjoyable.
