Ooh! I like this thread. I'm amazed at some of the things people think to post here. I'm assuming you have a slightly low teen's voice, with just a hint of gravel* to it. I assume this because most people who play a variety of video games (I see 3 already) have this sort of voice.
*Weird terminology I use. A sort of low growl from the bottom of your throat. Like when Santa talks. But I think this kids voice sounds like a deep teen voice, just a bit more hearty.
