Heroes VII

This problem actually appeared with the fifth installment. I don't see any improvements compared to the sixth.

Well, then I suggest taking a screenshot showing the hero's full movement range and counting how many useful objects and neutral creatures fall within that radius. I haven't done this myself, but I think the difference should be significant.
By the way, in the fifth game, I wouldn't say that everything is bad. The density of objects is reduced compared to the third game, but the movement range is also significantly larger. This doesn't fully compensate, but I'd say it compensates for about 70%. It's okay.
