I realize I'm necro'ing this old thread...
But I think the ST versions looked so damned impressive because they had a sort of trick overlay. You could notice when you move the mouse from the upper/scene area of the screen, and then moved it down over the character portion, it'd change colors. The Amiga version did not do that, since it could display 32 colors normally. I studied these visually for quite some time, they looked pretty much the same except for that mouse color changing.
