Carl Williams writes, "It is a rule of gaming, when one game is a hit, there must be a sequel to capitalize and cannabalize sales. SNK was no different in this regard as their unstopped rampage through fighting games on the Neo Geo system attested- as the system went on, fewer and fewer original games were released as sequel fever took over. King of the Monsters was popular enough to spawn one sequel, King of the Monsters 2: The Next Thing. King of the Monsters 2 was not perfect, neither was the original. What it set out to do though, it did well."
