The Amiga CD32 featured hw-accelerated chunky-planar conversion. And yes, the PC was an open system but this also meant that every MS-DOS game had to implement its own hardware-specific routines targeting multiple types of graphics and sound hardware. The Amiga approach came with the benefit of having a single, uniform target which encouraged more optimized coding.
I didn't know that! However the CD32 was at that point in history (1993) a blip, it was far too little far too late. It sold 125,000 units, while the PC clone market was shipping 37 million units in 1993.
I agree fully with the OS issues, but for the purposes of gaming, it turned out to not be an issue really I guess..
