Would Borderlands (2) be as much fun without the voice acting? I love both the lines and the delivery on Patricia Tannis, but I’m not sure how well the lines work without the delivery. There are some other performances I cannot cite without mild spoilers (feel free in the comments), so let me add that she was also great as the Firehawk, and I may need to go back and play Lilith in BL1 to hear what she does there. Marcus Mauldin also gives great delivery as the Slab King, and I may need to play Brick in BL1 to hear his performance there. Which is funny, because those two were the melee characters and so of less interest to me.
Colleen Clinkenbeard is the sorceress in the Orcs Must Die! games, also great work. Hey, the OMD warmage is also the voice of Axton? Hmm, I may need to try the BL2 Commando.
