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

So, if I call "Heroes 4" a parody of the great game ("Heroes 3"), will I become your sworn enemy and won't live long?

No, that's not what I meant. Heroes 1, 2, and 3 are very similar, and they differ significantly only from Heroes 4, while Heroes 5 is similar to Heroes 3, but with some minor changes!
