The company's first product was the science fiction-themed "Cyborg Commando", designed primarily by Mentzer based on notes from Gygax, which was published in 1987. New Infinites began working on a third line of products, which began with an adventure written by Mentzer called "The Convert" (1987); Mentzer wrote the adventure as an RPGA tournament for "D&D", but TSR was not interested in publishing it. Mentzer got verbal permission to publish it with New Infinities, but since the permission was not in writing TSR filed an injunction to prevent the adventure's sale, although the injunction was later lifted. The next project was a new fantasy role-playing game spanning multiple genres called "Dangerous Journeys". It was originally to have been called "Dangerous Dimensions", but the name was changed in response to the threat of a lawsuit from TSR, Inc. who claimed that the "DD" abbreviation would be too similar to "D&D." When the product was released by Game Designers' Workshop, TSR immediately sued for copyright infringement. The suit was eventually settled out of court, with TSR buying the complete rights to the "Dangerous Journeys" system from New Infinities and then permanently shelving the entire project. This led to the demise of NIPI, and Mentzer decided to leave the game industry.
