This is very tough territory for all involved. I was hired to replace Michael Beattie as Mordin Solus in "Mass Effect 3." I had never played the game, so I didn't even know I was replacing someone. I found out when I showed up to the session. My agents had sent me the audition, referring to it as an "alien scientist," and included a sound sample, which is not unusual for established IPs. I thought, "Oh, this must be how this species sounds, so I'll try to sound like that."
Initially, I caught a lot of ME fan hate for taking that job. Then, people played the game and seemed to adjust. Michael Beattie was very kind about it. When fans asked him if he would be involved, he simply said, "No," without trying to make life harder on me or Bioware. For my part, I always correct anyone who mistakenly says that I created the role, or that I played the character in ME2.
Jennifer Hale is one of THE premiere voice actors in the business, so it isn't like they hired a hack to save money. I don't know the game, or this particular character, but in my experience, $4,000 is a good offer for a couple of sessions, which is all most games require. It would be considered over-scale by union standards, and I'd be pleased to get it. I'm not sure what Ms. Taylor means when she refers to a "living wage." We're contractors, so we're paid per session. That's NEVER enough money to live off of one gig for any length of time. The presumption is that actors like us will be doing multiple sessions per month for different projects, which CAN add up to a living wage. That doesn't always happen, of course, but that risk comes with the territory. Most actors know and accept it. Working actors (not stars) are like professional gamblers: we hope to win enough games at enough casinos to piece together a living. Sometimes we do, sometimes we don't. That's just how it works.
