ME2

It took a while to get into Mass Effect 2 because it's quite different, but well into it now.

Bizarrely, I think it just referenced Saints Row 2. At the beginning of Saints Row 2, your character has just escaped from jail and someone says to him that they thought he was dead. He says 'Yeah, I've been getting that a lot,' and scratches the back of his head. Just now, someone said the same thing to Shepard, he said the same thing in reply and scratched the back of his head in exactly the same way.

How strange. Perhaps just co-incidence.
