Just me, or does this game look pretty awesome? Team Dakota, the creators of Project Spark announced that players could capture their own voice, and customize the audio the way they like it. It's pretty unnecessary, and isn't mandatory in a game, but it's still a pretty cool feature. You can also use motion capture for facial animations, body motions, create custom character animations, dialogue, and cinematic cut-scenes. You are also able to make your own attacks and a lot more.

Voice and motion capture enables:
Facial Expression Capture – Users can record their face and have it applied to an in-game character
Animation Recording – Do a new attack, full body motions, gestures, etc.
Record audio and modulate – Speak a line, singing, etc. Modulate the sounds in a variety of ways
The result is being able to make your own animations or even cinematic cut scenes when you combine all three (face + body + voice).
