The action role-playing series Ys (pronounced “ee-ss”) is one long, continuous adventure cut into digestible pieces. The Oath in Felghana, in particular, acts as a remake of Ys III: Wanderers from Ys, which developer Nihon Falcom released in 1989. The updated version came to PSP in 2010 with a localization courtesy of Xseed Games, but the game hit Steam only last month. Is it worth the $15 price point? For gamers looking to tap into the market of shorter RPGs (10-15 hours in this instance) or anyone seeking a good challenge: yes.
