Definitely will be including those versions in the follow up to this article. Reposted it here to gauge interest in putting together another part. I personally enjoy writing these articles because you can learn so much about other platforms.
I am in the United States so I never got to experience the MSX, Spectrum, Amstrad, etc. Those are all brand new platforms to me and there are a lot of good games on them as well.
Oh, that TG-16 version of SFII is pretty impressive. If only TTI could have pulled that off as a pack-in with the Turbo Duo back in the day - they might have faired better in North America. Sadly, they were not able to bring any big name Capcom or Konami titles over.
