During the 8-bit gaming era, Nintendo, as a form of quality control, regulated the number of titles to appear on its console, the Nintendo Entertainment System. As a result, companies like Acclaim used divisions such as LJN to produce more products than Nintendo would have traditionally allowed. Konami also utilized such tactics with their division Ultra. Unlike Ultra which was a brand name of Konami, LJN was still a legal company operating independently from Acclaim. Even after Nintendo dropped its rule in the early 1990s, Acclaim kept LJN operating which published several titles for the Super NES.
There is no video game that has been developed in-house by LJN. All of LJN's video games were developed by external developers, although many of their video games (especially the pre-Acclaim ones) did not disclose the developer.
LJN, along with the Flying Edge and Arena Entertainment labels (the latter two labels which published Acclaim's games to Sega's consoles) were folded into Acclaim in 1994.
