"Heroes 5". But are they really "Heroes"?

If the developers had said they would be releasing patches for the game 10-12 years ago, they would have been shot and no one would have bought the game regardless of how good it was (a prime example is Daggerfall, known among the people as Baggerfall). Nowadays, releasing patches and other fixes is the norm for ANY company. This is linked to the development of computer technology and many other things. Nival has first and foremost created a very solid foundation, upon which additional maps and so on will be built (if Heroes 3 had been released with 15 maps back in the day, you wouldn't even remember them now 8)).
The game is just a game; it is NOT UNFINISHED, there is simply a lot of empty space right now. It has excellent balance (unlike its predecessors), a great atmosphere, graphics, modding capabilities, etc.
P.S. Heroes 5 is an excellent addition to the series.
