Yet another problem was that most of the games that were available were developed in Taiwan or Hong Kong, meaning that fans of big-name Western and Japanese developers were underwhelmed by the apparent lack of support from these companies. Only a tiny handful of games were developed by third parties, including Sachen and the British developer B.I.T.S.. Up against Nintendo's list of popular franchises (Zelda, Mario, Metroid) and those of its third parties (Castlevania, Mega Man) - all of which eventually surfaced on the Game Boy - the Supervision's games were of little interest to most.
