Ys Complete - Opening

Ys (イース, Īsu?, IPA: ) (English IPA: /ˈiːs/) is a Japanese-origin computer role-playing game series, and Nihon Falcom corporation's flagship franchise. It started on the NEC PC-8801 in 1987. Ys titles appear on the MSX2, Sega Master System, Sega Mega Drive, Famicom, Super NES, PC, PlayStation 2, TurbGrafx/PC-Engine CD-ROM, and cellular phone. The common misspelling "Y's" arises from a typographical error in the packaging of the English-language versions of the Sega Master System.

The Ys series chronicles the adventures of Adol Christin, a red-haired young man from a Germanic country with a zest for adventure and an uncanny knack for being in the right place at the right time. Gameplay always revolves around Adol, though his comrade, Dogi, is a frequent companion in his travels around Esteria. Adol is the only truly playable character in the series. Feena was a non-controllable companion in Ys Eternal, and Tarf was set up in Ys II ETERNAL. Several characters follow Adol in Ys IV.

The standard gameplay mechanisms involve the control motion pad to fight, i.e. pushing the enemy until dead. Those gameplay mechanisms were done away with by the game's fifth installment, Ys V: Ushinawareta Sunano Miyako Kefin or Lost Kefin, Kingdom of Sand. Ys VI: Napishtim No Hako or The Ark of Napishtim graphically departed from its predecessors, using three-dimensional graphics and hack-and-slash gameplay. The Turbo-Grafx games (particularly Books I and II) are considered the best of the series by the older fans of the original series.
