After Nihon Falcom released the first three installments in their Ys series of action role-playing games, the installments proved popular enough to make appearances on nearly every active console from the Nintendo Famicom (NES) to the Sega Mega Drive (Genesis). Even if it was virtually unknown in the West, the series’ domestic success ensured the inevitability of a fourth installment. Unfortunately, the success this series enjoyed came at something of a cost. After the release of Ys III: Wanderers from Ys, a substantial chunk of Nihon Falcom’s staff members quit, thereby depriving the company of the resources needed to produce a sequel. They were in such dire straits that they couldn’t even provide a full script for the game. Their contributions were limited to providing a vague outline and composing the music. They handed off what they could get done to Hudson, the company that published the highly praised compilation Ys Book I & II.
As Hudson collaborated with Alfa Systems on a game entitled Ys IV: The Dawn of Ys, Nihon Falcom pitched the idea to other studios so they could create versions for other prominent consoles. One such developer was Tonkin House, the company behind the SNES port of Ys III. Another was Sega, with whom Nihon Falcom had entered a partnership to port their output to the Mega Drive (Genesis). They even allowed the Korea-based developer Mantra to develop their own version of Ys IV. Mantra had released a highly successful version of the series’ second installment named Ys II Special, which greatly expanded upon the source material and included more secrets than any other version of the game. However, Sega’s version was canceled before it could get off the ground and although Mantra considered the offer, they ultimately declined.
Other than The Dawn of Ys, only the version developed by Tonkin House was making significant headway. Their take on the series’ fourth installment was named Ys IV: Mask of the Sun. Though both developers pushed for a release in late 1993, Tonkin House cut Husdon and Alfa System at the pass by releasing Mask of the Sun one month ahead of The Dawn of Ys. It was released to a fairly lukewarm reception with Famitsu, the most widely read gaming publication in Japan, awarding it twenty-five points out of a possible forty. Was Tonkin House able to do Nihon Falcom’s increasingly venerable series justice?
