Hey guys sorry to double post but these are 2 totaly different ideas. I have absolutely no voice acting skills and im trying to make a well played machinima lol. Its very serious so should I do it all on body language and surroundings or is that what makes it bad. I dont have enough connections to get voice actors and I dont have a good enough mic. If you have any suggestion I would love to hear them, once again sorry for the double post and this is not an advertisement by any means.
