And it's a big voice cast at that, considering you've got all the main character voice actors from Mass Effect 1 and 2. There looks like there are a couple of new additions though (I guess a couple of more potential romantic interests?).
Freddie Prinze Jr and Jessica Chobot (who is apparently an IGN host and staff writer) join the cast. It must be a dream come true for gamer girl Jessica to actually star in such a high-profile game like Mass Effect 3!
