When should I look for voice actors?

Holy hell, I go to bed and wake up to a million posts. LOL. Yeah, I personally don't see voice acting as a big deal. But pretty much everyone I've watched LP my last CS has mentioned that it would be better with voice acting and I've received plenty of reviews that docked points because of it. Personally I just want to put a message at the beginning of my CS that says "There is no voice acting in this. If you can't read, go play call of duty or something." but I'm trying to remain civil.
