Regarding sounds, I'm on both sides of the fence. Sometimes, I want sound because it makes the item feel "complete". But other times, I want accuracy, and we all know most screen-used props don't have sound in them. So I'm kind or glad that SAT didn't add sound to this SI in order to preserve the accuracy. However, sounds would have been nice so I won't have to go "pew pew" when pulling the trigger.
