RPGs
Following an introduction to GURPS in Steve Jackson's Man to Man, C.J. Carella got his first work in the role-playing games industry on GURPS Martial Arts (1990) and freelance work for Steve Jackson Games. Carella designed GURPS War Against the Chtorr (1993), which game designer Rick Swan called a "first-rate supplement for the GURPS game". He also wrote GURPS Voodoo: The Shadow War, published in 1995.

Carella then became a staff members of Palladium Books. He created the Nightbane setting and was involved in the production of Mercenaries and Pantheons of the Megaverse for Palladium's multigenre RPG RIFTS. Carella also wrote Rifts Manhunter (1996), which was published by Myrmidon Press as a cross-book between their own science-fiction game Manhunter and Rifts. Carella designed the role-playing games CJ Carella's WitchCraft (1996) and Armageddon: The End Times (1997), which were first published by Myrmidon.

Carella developed the Unisystem for the first editions of WitchCraft and Armageddon. Carella had negative experiences with Myrmidon on their business end, and since George Vasilakos and M. Alexander Jurkat of Eden Studios, Inc. were fans of his work, they had talked with Carella about developing a crossover book for Conspiracy X and Witchcraft.

Conspiracy X supplement sales were dropping by 1998 and so Eden Studios wanted to add more lines to revitalize the business and got an exclusive license with Carella to publish his WitchCraft and Armageddon role-playing games. Carella created a simplified Unisystem variant for the Buffy the Vampire Slayer Roleplaying Game (2002) named the "cinematic" system. Carella wrote Secret of the Ancients (2003) which was the final volume of the Odyssey adventures series from Eden. Carella also co-designed Eden Studios' RPG Terra Primate.
