I was actually trying to decide which storyline I liked the best. I sort of agree that Connor has the most interesting one, but without Markus you wouldn't have the last few chapters where everything comes together and some of his missions are really fun. But Kara and Alice are absolutely the emotional center of the game. If it weren't for their story I don't think the androids would gain nearly as much empathy from me. They really bring the humanity to the overarching android debate.
