Because Wrestlers Are Scary!

LJN/Acclaim pioneered licensed wrestling games on the NES, and continued their successful series with WWF Super WrestleMania for the SNES.  But they opted to promote the game with a tagline better suited to a horror game:

Now, I'll agree that Hulk Hogan's muscular man-breasts are a tad on the frightening side.  But he's clearly ripping his shirt off himself, completely voluntarily and without the aid of any pulsating, hydraulic alien growth or impending oozy transformation.  And his "fierce" expression makes him look more likely to guzzle a huge glass of cold lemonade than to rip out anyone's spine or swallow one's soul.

Some of Hogan's fellow wrestlers are a little scarier, or at least seedier.  But note that the only photorealistic representations of these wrestlers appear on the ACTUAL GAME SELECTION SCREENS!, and the ad plays down the screenshots of the cartoonish in-game versions, devoting more space to photographs and hyperbole.

SO REAL YOU'LL WISH IT WAS JUST A GAME!

Laziest.  Genie gig.  Ever.
