This has always been my view; It's the only CPU I know about that met the requirements.
Other 16bit consoles used an off-the-shelf 68000, combined with custom support chips. Nintendo made their own custom cpu silicon, an off-the-shelf soft-cpu and custom support logic for bus control and DMAs.
And there simply weren't that many 16bit soft-cpus available for Nintendo to license. You couldn't license the 68000 HDL, nor the 8086 HDL.
