Why's it crazy talk! What, do you prefer the CGA graphics of the DOS one? I dunno about you but 4 colors (black, gray, teal, magenta) and no music aint my bag.
Sure you can add the EGA patch w/ wavetable music, but that is a fairly recent addition (fan made) so it doesn't exactly count.
so that'd leave the other old computer versions. The C64 could POSSIBLY be said to be better, if you play it on a C128 and experience the SID music, and are ok with disk swapping like mad.
The NES/MSX one condensed the commands down into menus smoothly, kept the geography and story the same, and spiffed things up graphically. Plus the music is pretty catchy.
The MSX even did that for Ultima IV. A pretty nice PC port on 3.5" disks with no irritating swap fest to be had.... and MUSIC! The PC one didn't get music til someone made that VGA patch.
and the C64 version had no music unless it was on a C128.... so...!!!!
SMS/NES/MSX did ultima 3 and 4 justice!
....and dropped the ball completely with Ultima V. Oh sweet lord was it awful.
