If "Genesis Does" was the first strike, "Welcome To The Next Level" was the full-on assault that ultimately helped SEGA win the 16-bit wars with their hip and edgy commercials that made Nintendo's Super Nintendo look like chump change. This Sonic 2 ad from 1993 stands out for breaking away from the form that SEGA themselves had established; the sign of confidence and success is being able to break away and experiment.
Despite SEGA's very assertive campaign for their 16-bit machine, Nintendo was still on top of the world with their 8-bit behemoth, and their ad for Super Mario Bros 3 is a sign of this. Not only did it address its primary demographic, but it spoke of a confidence that they were (at least at the moment) the king of the hill.
The SEGA Master System was a bomb during the mid 80s and they was determined to not let history repeat itself with their follow-up, the Genesis. The 90s marked the beginning of a brand new, more aggressive marketing campaign, which was also aimed at a slightly older audience. SEGA's "Genesis Does" campaign was the opening salvo of what would be easily the most colorful console war that gaming has yet to see.
