Sega Mega Drive/Genesis

The Sega Mega Drive (called the Genesis in North America due to legal rights) is a fourth generation console with 16-bit graphics developed and released by Sega to compete with the Nintendo Entertainment System and the Super Nintendo Entertainment System. Sega later decided to replace Alex Kidd and come up with a new mascot, which turned out to be Sonic the Hedgehog. Sonic the Hedgehog 2, which was sold with the Genesis version 2, came out to be the bestseller of the system. Although the Mega Drive didn't beat the Nintendo Entertainment System (copies sold-wise), it went on to have a great impact on the video game industry, even ranking #5 on IGN'S best video game consoles of all time list.
