COMMAND & CONQUER 3:Tiberium Wars
Mass Effect 2
Courtenay Taylor as Jack/Subject Zero
Mass Effect was very pretty, and featured top-notch voice actors. Mass Effect 2 is even prettier still, and the new additions to the cast give the original rogues' gallery a run for their money. Courtenay Taylor is delightfully vicious as Subject Zero.
Courtenay Taylor as Scrin A.I.
Courtenay Taylor also lends presence as the alien Scrin A.I. You might not know her name, but you probably know her voice from Supreme Commander, Knights of the Old Republic, Call of Duty 2, and God of War. She played the twins in the game's...controversial mini-game. - CRAVE/CNET.com
KNIGHTS OF THE OLD REPUBLIC (KOTOR)
Courtenay Taylor as Juhani
Part of the reason the story works so well is that it has some outstanding characters. The cream of the crop is the nine non-players characters (NPCs) that join your party...Most of them have well-written dialogue and fantastic voice acting, making them seem more like a movie character than a game character. There were three that really stood out to me: Mission Vao, *Juhani*, and HK-47. Juhani is a Jedi that fell to the dark side, but...once again walks the path of light. Her struggle with the dark side isn't over and it's interesting to watch her tread the line. - Gamespy.com
