It seems like in the first Heroes game, blood also gushed out everywhere. There weren't any skeletons, though; there were ghosts. Or maybe it was in the second game, where skeletons already appeared... I don't remember.
But I understand that there won't be as much emphasis on the unit models as there was in the fifth game and later. It will just be some generic guys running around the battlefield. That's a shame. For me, at the time, the large unit model taking up half the screen became the main "wow" effect of the fifth game. Before that, I was frantically trying to make out the models in 5x6 pixel windows, but then there was a beautifully rendered unit in full size, so you could just take a look and draw it.
