I voted NES, however I had (and still do) all of those. [:D] Also, Dreamcast is actually a next gen console, even if it came out years before the rest! And that first Sega you listed is called "Sega Genesis"... of which they released three different versions (1, 2, and CORE) and two add-ons (I think) (Sega CD, and some 3DO addon).
