Keith David is in EVERYTHING though. Wish he'd say "Is it the frank or the beans?" in one of his appearances.
When he popped up as Julius in Saints Row I thought "Cool!", then as Captain/somerank Anderson in Mass Effect I thought "...cool...I guess", but as soon as Sgt Foley started talking in Modern Warfare 2 I had to shout "How'd you get the beans above the frank?!" - still his finest moment.
Just noticed that Nolan North voices Desmond in Assassin's Creed as well.
+1 for Jennifer Hale, she's great.
