Sega Multi-Mega - Oh dear. The Multi-Mega, known as the CDX in the US, was a 1994 release that hoped to make Mega Drive gaming look a little more sleek and modern by slimming it down in the casing of a discman, or portable CD player. A tiny device not much larger than its CD drive, the Multi-Mega could play Sega CD and Mega Drive games. Woefully expensive and utterly pointless, it was the last full-price Mega Drive console offered by Sega, and as such is a sad chapter to close out one of the best gaming consoles of all time.

Note that these are just some of the variations of the Genesis/Mega Drive released. Both Sega and other companies have put out a number of cheap, retro "re-releases" of the hardware, some dating as far back as the late 1990s (the Genesis 3) and others still being released "new" to this day.
