Ditch this union thing and use your friends as voice actors. You are an indie dev, people don't buy your games because of AAA quality. Besides, sometimes I have heard professional voice acting so devoid of any relation to the game (I would never give voice acting to someone who has not played my game) it made me wish the team did it instead no matter how incompetent voice actors they are :D
I know what you mean, though the actors I have available to me are pretty top notch (and friends & also family of friends) so it'd be awesome to have them in the game if possible, without A) getting them in trouble with their unions or B) getting us in trouble/or spending too much $$ etc. -- Also i definitely want to be able to put our own voices in the games, as well as friends/girlfriends, whoever we want.
We'll do what's best for our game and budget ultimately - just wondering if anyone has had any experience or advice on this stuff. Thanks for your input! Anyone else?
