I am a HUGE fan of the Forza series. But I hate playing racing games with a joystick, and I don't have the space for a real steering wheel & pedals. So the XBox 360's "Wireless Speed Wheel" was perfect for me.
Microsoft lost a customer when they released XBox One without support for XBox 360 controllers and no replacement for the 360's wireless speed wheel. Leaving behind the XBox360 controllers was a blatant money grab, but if they'd have come out with a replacement for the WSW, I'd probably have paid full price & bought the box on launch day. As it is, I still play the original Forza on my 360. And when I needed a next-gen console, there was no reason not to buy the PS4.
