There’s one area where PC gamers get consistently overlooked: haptics. Haptic feedback (or rumble, in the vernacular) has been a mainstay of console gaming for almost two decades now, and for good reason. Smart usage can both increase immersion and provide invaluable feedback to players, e.g. letting you feel the moment digital tires lose traction on slick asphalt, or warning that an enemy’s shooting at you.
There have been a few experiments, like SteelSeries’s Rival 500—a mouse with built-in haptics. But it’s hard to make a mouse with rumble because it’s bound to affect your aim, and keyboards are too large and heavy to effectively produce the effect.
