Who cares about copper lists colour++, SOTB, jim power, elfmania.. all of them where mediocre games with tiny screens.
Most of the good amiga games would have gained more from having the megadrives 64 colours and actually scrolling functionality. Cannon fodder, sensible soccer, alien breed, Xenon 2.
The thing that made amiga beat the megadrive wasn't specifc copper tricks games with theoretical color advantage but 4 color sprites. It was the fact that smaller publishers could create games without payning a lot for expensive dev-kits and licensing. Games like Sensible soccer, Pinball dreams, Civilization, Wings, Lemmings would not have been published on a console platform.
