I've got a vague idea about "Nod" one:
We were discussing Hand of Odd, someone pointed out that that sounded a bit like "Hand of Nod" on Command and Conquer, someone else thought (likely by not reading stuff properly...
You know who you are...
(j/k)) that the person had said Hand of Nod was the next game after ME (or something like that) and it stuck.
I was never sure if it was an actual title of an upcoming game or not... Still don't. Anyone...?
