That's so shortsighted it hurts. The CD32 _is_ an Amiga, so the games weren't ported (unless it was from other platforms)... The concept behind the CD32 was to be a low-cost alternative to an Amiga 1200 designed just for playing games, but you COULD expand the console to a full A1200 with an expansion module called the SX-1 (if I rememeber correctly).
Yes thats true partly, i dont think commodore wanted it to be expanded into a A1200 even though the public wanted it, they did start to do one that sat underneath the CD32 but never got released due to Commodore US going belly up, i'm currently doing a cd32 list (and will restart my ngcd one!) that will give all details of exactly how many A500, A1200, CDTV ports it had with what cd32 extras were added and the CD32 exclusives - not too many of those, but even look at the jaguar that had ports of amiga games no one moaned at those even at £50 a game!
The CD32 had 3 add ons, SX-1 that stuck out the back, SXMK2 that could add a processor etc and SX32 that had a built in '030 50mhz processor and extra 8meg ram.
Don't forget the FMV unit, i've still got mine on the other side of the country at the minute but are quite hard to get hold of even when they came out.
Overall at the time it was an exciting console that could be expanded to play floppy games etc, still has the best start up screen on any console, sure most the games have outdated bar a few that still hold well, but the amiga was about playability.
