I'm really surprised that only a few people mentioned sports games. Sports games were, by far, the number 1 reason to own a Genesis back in the days. It was widely accepted that just about every sports game was far superior on the Genesis, even though the SNES version usually looked slightly better due to colour depth.

I guess no one really plays old sports games much these days... but here in Canada, people still argue over the merits of NHL 93 vs. NHL 95... and it's always the Genesis versions they're talking about.
