Nolan North is Deadpool...
The main unitologist guy in Dead Space 3 looked familiar and made me think of a character called Larry Bird in a tv show The Neighbors. Saw him again and had to check it out to see who voiced the guy; it turns out he is voiced by the guy I thought he reminded me of - an actor called Simon Templeman.
Turns out he's done alot of voice work for games and alot that I have played too - Darksiders 2, Mass Effect 3, Kingdoms Of Amalur, Uncharted, as well as Kain from The Legacy Of Kain/Soul Reaver games.
And all this time I thought he was someone I didn't know in The Neighbors.
Now we know.
