Overview

The Sega Mega Drive (Genesis in North America) was Sega’s declaration of war. Launching before Nintendo’s 16-bit console, it grabbed market share, attracted third parties, and positioned Sega as the cool alternative. Sonic the Hedgehog sealed the deal. For a moment, Sega and Nintendo were equals.

Legacy
