There's a lot bias in the gaming press about the Genesis's capabilities. I guess most of these writers were Nintendo fans.
Looking back though the Genesis was a marvel of engineering for the time--ultra crisp RGB native output still amongst the best after all these years, 68k processor that was pushed for nearly a decade, and great sound chip and sound capabilities.
I loved both systems, but Genesis seemed to be more future proof looking back.
In retro-related general gaming press I've noticed this extremly recurring compulsion to add in some unneccessary disclaimer or back-handed compliment when talking about the Genesis or games for it. Stuff like "this is pretty good, for being on Genesis". I see it happen so many times it makes me wonder why they don't think about what an utterly redundant statement it is. It gets really grating after a while. I can't think of any other system that gets treated this way in retrospect.
