I completed the main story before I even did a couple homestead missions. Anyhoo, this lead to a pretty epic time paradox when I finally started playing through them. I had to get my time line straight. Because at the end of the story, it makes things pretty clear that Achilles is dead. Of course, I just went along with it because that's how subtle I thought the game was being about it, but it turns out you get to see about ALL of that as you progress through the homestead missions.
As you may know, prior to Achilles death in the homestead missions, Connor at most will only jog through the house; however, after Achilles death suddenly Connor sprints through the house. This made me LOL because Connor's basically like, "Yo, the Old Man's dead. I'ma do what I want."
Anyway, I just wanted to share how hilarious I thought that was!
