Making different and unique hardware can be great. But it isn't when the hardware isn't reliable or utilized in interesting ways.
Motion controls have been mainstream on console since 2007 with the Wii and hardly any games since have utilized them for anything very not worthy. qte, aiming and minigames. Kinect has exist since, like, 2010? You could probably name less that ten games that relied heavily on Kinect that were actually good.
So yeah, this isn't a tragedy at all. Unique hardware can be great but not when it's failed to justify making a system one hundred dollars more expensive that it's competitor and not when that hardware is synonymous with incompetence.
