To be honest, I really don’t think there’s any reason to worry about a boring game. You’ll need to survive in the first step, facing the wilderness. There will be plagues, etc. In later stages, there will be enemy raids to face off, maybe diplomacy and politics issues to look at, etc.
And if this ending event around the Indo-Europeans coming to crush (or reinforce?) your settlement is implemented, we’ll have a grand finale that will be a total surprise for the noobs, but also a real accomplishment to face when being an experienced player, orienting a part of their replay games, etc.
Really, I see lot of potential in A.C. that make me believe we won’t have time to bother, just lacking time to play and test every possible strategy 
EDIT : I said exactly the opposite of what I intended in my first sentence
