The previews state that the earlier ages are more about magic and the later ones more about armies.
In Dom 2 it was the other way around, because it took so long to get to the point where summoned SCs with magic weapons would dominate normal armies.
So, has this been changed in some way, or did the previewers get something wrong?
Besides, remember that one turn = one month. So even 2 ages would be 2400 turns. I don't think anyone (except Gandalf, perhaps?) would like to play as long.
