(but the hardware differences between an Megadrive and Amiga aren't that big, aside from the sound)
Don't get ahead of yourself... =) ...programming for the MegaDrive should be way easier than programming for the Amiga, especially considering handling different layers of graphics. Not that MegaDrive is a particularly fantastic console, but making an Amiga version of, let's say, Sonic The Hedgehog 3 would probably be pure hell especially considering the many different layers of graphics, parallax scrolling, high-res 2-player mode and so on and so on (although probably possible to do). I think people often believe they have more in common than they actually do... because of the 68k.
--- PERSONAL OPINIONS AHEAD ---
Oh,and considering Moonstone... it is just one of those really over-rated games for the Amiga. Wasn't particularly bad for its time though, a mixture of a figthing/adventure with some classic gore scenes with lots of blood and so on and so on. It hasn't stood the test of time, and feels extremely dated today... the characters move extremely jerky on the screen, there is no saving enabled and you can pretty much, if you are unlucky, reach far in the game with no problems at all and then suddenly die and die and die just to do it all over again. I don't know about all versions of the game, but some were really buggy and had a tendency to crash in the most inappropriate times. The overall impression of the game today isn't exactly what it was back in the days.
