Fun fact: Many think this achievement would go to the original Xbox. But the Nintendo Gamecube beat it by two months in Japan with their September 2011 release. If this wasn't enough however, it's pretty well accepted that the idea for an analog trigger on a controller came from the digital trigger on the Nintendo 64 known as the Z-button.
The idea behind an analog trigger was pretty groundbreaking, even if we don't realize it today. An analog trigger allows for gradual pressing, making the varying degrees of "squeeze" do something different. This is all thanks to the Gamecube controller.
