Forza Motorsport 5
The Xbox One's impulse triggers are an important distinguishing feature for the console, but they are difficult to appreciate without holding an Xbox One controller in your hand. This video with Forza 5 developer Turn 10 attempts to explain their importance and how they provide feedback to the player.
I wouldn't be surprised if after the release of the Xbox One and the PlayStation 4, the Xbox One's impulse triggers became a large bullet point advantage amongst debaters for Microsoft's console over Sony's. My experience with the triggers has been brief so far, but they are very efficient in changing the way interaction feels.
You can check out the video below where Xbox Live's Larry Hyrb and Turn 10's Dan Greenwalt talk about the triggers and how they influenced the development of Forza Motorsport 5.
