This is a 1080p version of the full comparison chart I made for JCG018 Ultima IV: Quest of the Avatar. That video is available here:    • JCG018  Ultima IV: Quest of the Avat...  

It is going to be a long one... however, in the mean time, I finished up this version comparison chart showing differences between 16 versions at a time (technically 18, but I explain that at the beginning). The music cycles between them, with a little golden sound icon showing which is playing when.

There is so much going on in this video, it would take many viewings of the comparison to be able to properly compare them.
