I'm a huge fan of the Amiga, and I definitely try to favour it (and the C64 ) as much as possible. However, note that we're talking about the 16-bit Apple II
gs port here, not the inferior 8-bit Apple II version. As far as I can tell, the Apple IIgs port is graphically identical to the Amiga version (including animations), and the music is actually vastly superior. Also, it's not heavily bugged as the Amiga version (as evidenced
here and
here), which makes it the only bug-free 16-bit port in existence (I hear the C64 originals are also bug-free). That's the reason why GOG apparently sells the Apple IIgs version of Bard's Tale I & II.
