Because 90% of the shit that would have made the game understandable and aided in character development was scrapped. Connor's monologue after finding Haytham's journal. This. Achilles history with Connor's mother. Haytham's personal quest to find his sister and his vendetta against Birch.

All that shit got shoved into either deleted material or Forsaken, when it should've been in the game.
