The cartoon referee who officiates in-game matches is a caricature of Brian Hildebrand, who worked at World Championship Wrestling as a referee under the ring name "Mark Curtis" from 1995 to 1999. The game's manual identifies the referee as such, using his "Mark Curtis" ring name. Hildebrand would pass away from stomach and bowel cancer eleven months after the game's release.

For years, players were puzzled by the inclusion of wrestler Scott "Raven" Levy on the game's cover art, as despite his cult icon status in Extreme Championship Wrestling, Raven wasn't as big of a superstar in World Championship Wrestling compared to the other three wrestlers on the cover: Hollywood Hulk Hogan, Kevin Nash, and Bill Goldberg. In 2020, Raven would clarify on Twitter that he was included on the cover simply because he was THQ producer Sanders Keel's favorite wrestler. Levy also joked that "the Illuminati were recruiting [him]." An interview on the Insider's Edge podcast with Keel confirmed the story, having been a fan of Raven's since his ECW days. Raven's inclusion also helps highlight the game's main four factions: WCW (Goldberg), New World Order White (Hogan), nWo Red/Wolfpac (Nash) and Raven's Flock.

Some songs in the game's soundtrack are MIDI renditions of actual songs by bands such as Van Halen, 311 and Steve Vai. This was done to avoid any copyright issues.

The EWF group all had different names in the game's beta and were changed in the game's final release. The characters represented real life non-WCW wrestlers at the time and were likely changed to avoid paying royalties to the wrestlers.
