PlayStation Move

The PlayStation Move remains the most redundant motion controller of its generation. Launched in 2010, it arrived three years after the Wii had already demonstrated that motion controls had a limited lifespan, yet Sony committed to a glowing orb that required a camera to function—a setup far more cumbersome than the Wii Remote's built-in sensor bar. Dedicated games were scarce, with fewer than 20 titles taking meaningful advantage of the technology, compared to over 500 for the Wii by 2011. Its long-term failure is underscored by sales: the Move sold roughly 15 million units worldwide, less than half the Wii Remote's 40 million in the same timeframe. Sony later repurposed the technology for PSVR in 2016, but even that revival yielded only marginally better results. Ultimately, it's a device that never justified its existence.
