There are so many excellent voices that trying to choose is difficult! My favorites would include the agent's voice, the knight's voice, the warrior's, the inquisitor's, and the smuggler's. I like the other character voices as well, but those were the ones that I liked the best. As for the companions, I like Xalex, Corso, Torian, Kaliyo, Akavi, Quinn and Vector in particular. I've heard several voices in the quests that are excellent, such as the Emperor and the Dread Masters. They sound so deliciously evil! I also like Master Syo's voice and Darth Baras and Darth Marr's voices. There's a quest on Nar Shaddaa with a dark jedi names Ako Domu that had a voice I really liked. I've been trying to find out who did it since the first time I did that quest. Master Orgus and Col. Yudrass also have great voices. So does Keeper/Minister of Intelligence. Another voice that I love is Scourge, I wish he was the romance option instead of Doc just for his voice......sighs. I'll never be able to pick just one voice as an absolute favorite, but it's fun thinking about them!
