I was always put off by the color palette of the Mega Drive. Every game looks a little sad and drab compared to the SNES or NeoGeo.
Specifically the SMD global palette had limitations around desaturated/pastel colours, with choice in saturated colours. And with no sprite blending, opportunities for subtle tones are further limited.
Sonic being the exception
