In the past we've examined the evolution of Nintendo commercials--now it's time to gape at the insanity of Sega ads.

Oh sure, there's been plenty of Sega strangeness lately, but nothing that compares to its previous work. With screaming dead squirrels, spleen-bursting games and Marky Mark to choose from, we've compiled a wide-ranging list of our favorites.

While it's in Japanese, this Chu Chu Rocket commercial jingle is still surprisingly catching. It demands that you "save the mice" because the "cat is scary" and the "rocket is awesome."

Ever wonder how Sega brought Virtua Fighter 2 to the Saturn? This Japaneses advertisement has the explosive answer.

An Inventive Approach to Color (link to this video)
Back before the Game Boy Color, Sega's battery-guzzling Game Gear was one of the only color portables in town. Needless to say, Sega made the difference quite clear.

Out of the Closet (link to this video)
This Japanese ad for the first Samba de Amigo on Dreamcast implies that you should check your closet for dancers before playing. You never know!

Genesis Does What Nintendon't (link to this video)
Michael Jackson, Joe Montana, and some dude I'm fairly confident is James Douglas all personally appear in this classic Genesis commercial. How did Sega go wrong?
