If I had to describe Nintendo in just three words, I’d steal the shared city slogan of Austin, Santa Cruz and Portland: “Keep Nintendo Weird.” The Japanese game giant delights in its own unique character, and has made a habit of defying convention. Nintendo’s gimmicks are always fascinating, but they don’t usually work out. The Wii Remote’s speakers largely went unused. Most third-party developers failed to take advantage of the Wii U touchscreen. So, what’s Nintendo Switch’s soon-to-be-overlooked innovation? A haptic feedback system called HD Rumble.
