The Amiga was always kind of crippled in that, the machines shipped with low amounts of chip ram for too long as standard. So you were limited in what you can do. At least with the CD32 you had a standard set of resources to work with, every machine had a CD drive, every machine had the 2 megs ram. This gave the cd32 the most arcade like experience.
The CD adaptations of Amiga games were great becuase the sound tracks were upgraded to CD Digtial Audio wheras the CDTV spooled audio files off of CD, it did not support the extra audio tracks in game if I remeber correctly. They generally fixed any problems or added a little something not around in the floppy version.
It would have been great to have fast ram and at LEAST a 16mhz 030 or better... come on it was 1994 when they made the last batch.
