I could go on all day.
weren't you the one that owns only two CD games? how could you even judge the might power of CD-ROM²?
btw. I also went with CD-ROM², since it was the technology that pushed the system to its absolute limits. sure some hueys are great too in terms of showing the technical ability of the system, but the CD-ROM² just pushed it beyond the believable. great games like GoT, WoT, Drac X etc. wouldn't have been possible without CD-ROM² tech., and therefore I am very greatful.
and in the end it also prevented the system from dying quickly during the harcore 16-bit war, since it could offer so much more than the MD/Genny and SFC/SNES at that time could, due to its succesful add-on.
I sure love teh hueys very much, but as chris already said, it wasn't that super novelty that nobody had ever seen before. the CD-ROM² as a game media storage au contraire was something that the world hadn't seen yet at that time it came out, and was even a novelty for the upcoming years.
