An announcement to all Assassin's Creed players: Duncan is not going to betray you. You can stop glaring at him now.
In Awakening, who would've thought we would hear Zaeed Massani speak the words of the Joining?
Or that he'd be locked in a Civil War in Orzammar?
Or that he'd be the mayor of Redcliffe? Seriously, Robin Sachs voices way too many major roles, and it's even more noticeable if you know him from Buffy the Vampire Slayer, Galaxy Quest, or Mass Effect 2.
Mass Effect fans playing the Dalish origin may feel the urge to ask Marethari if they've gotten hammered together before.
One of the random dwarves outside Orzammar sounds like he's about to say this is his favorite stall on the Citadel. Also, a male Elf character with the Experienced voice set has had enough of your disingenuous assertions.
Shrug of God: When asked about Maric's cause of death, David Gaider repeatedly stated that it was irrelevant before finally revealing that he was lost at sea.
