WWF King of the Ring on the NES was so bad, no one even remembers it in this thread. Priceless. It easily had some of the more painful sprite work on the hardware. Hilariously underdetailed and a mass of lines and color. Gameplay was simply atrocious too.
I liked most of the LJN 16-bit games, beginning with Royal Rumble. The underrated Rage in the Cage on Sega CD is awesome. Great voice work that sold that era of the WWF. I could do without the "computer wins when it wants to" button mashing grapple system, but those games had a great move set.
