We will make western version RS3. It will be after the Japanese version. But, at first, RS2 Vita for West. I want your patience, please.
The localization of Romancing SaGa 2 is still in development for the PS Vita. The game features updated character, background and battle graphics, and the “Class” and “Original” dungeon” from the 2010 mobile version of the game.
The remastered version of Romancing SaGa 3 will have redesigned characters, backgrounds and system menus as well as new controls optimized for the PS Vita. Originally released in 1995, Romancing SaGa 3 is an RPG where the player chooses from 8 main protagonists to play as, each with their own story and playstyle.
