This lesson got relearned a few times by several different console manufacturers. The N64 was too elaborate; so was the PS3. Even the early commercial lifecycle of Amiga games consisted mostly of low quality Atari ST ports - and the Amiga design is much more "assistive" than "dependent" on its coprocessing, with the major features of the custom chips translating mainly to implementations of software functions in hardware, rather than a wholly different programming paradigm.
For a point of comparison, the final evolution of the ST line, the Falcon, had a programmable DSP. Released in the year previous to the Jaguar, this system proved to be capable of rendering Quake 2 levels, decades later. Would it have worked as a console? Probably not(a different cost structure applies to computers and this example was positioned at the high end), but a 1992 system that renders 1997 graphics somewhat competently is an impressive feat; this was the era when the transistor budgets became biased towards higher clockspeeds and the 18-month cycle of Moore's law was putting PC gaming through a "micro-generation" every two years.
