The Dreamcast was an odd system particularly with the VMU acting as a memory card that also had games on it (though it is kind of interesting though that the Nintendo Switch at least nominally borrowed this idea of an all-in-one regular console + mobile gaming experience). Dreamcast aside - the story of the rise and fall of Sega is pretty fascinating. They fragmented the hell out their product offerings - at one point in the mid-90s having seven platforms - Genesis, Saturn, Game Gear, Pico, Sega CD, 32X, and the 32X CD.
