I haven’t finished Mass Effect 2 yet; but it seems to me that there are a hell of a lot of quests that involve parent/child relationships. Miranda and her dad, Jacob and his dad, Thane’s son, Samara’s daughter, Tali’s dad…

Just an observation; I’m not sure yet if it’s a brilliant thematic device or laziness.

I’m sure other people have discussed this, but I’m not reading anything about ME 2 until I finish it.
