For what it's worth, the new Assassin's Creed game, Black Flag, is much improved over AC3.
I'm definitely enjoying the Edward storyline. I'm still iffy on the present-day story, but I still have quite a way to go - maybe it'll grow on me.
It won't. The present-day story may as well be removed from the game; it serves absolutely no purpose.
But the Edward story is a lot more fun than Connor's story.
