Following the reveal of a Nintendo Switch release in yesterday's Japanese Nintendo Direct presentation, Square Enix revealed that SaGa Scarlet Grace will also be released for PC (via Steam), PlayStation 4, iOS, and Android in Japan in the summer of 2018. The new version is titled SaGa Scarlet Grace – Hiiro no Yabou (the new subtitle translates as "Scarlet Ambition") and adds extra story scenario, new voice acting, new characters, new music, and other elements.

SaGa Scarlet Grace was originally released for PlayStation Vita in 2016 as part of the series' 25th anniversary celebrations and was the first new mainline SaGa title in over a decade. The game uses a strategic battle system and sees players choose between four protagonists, with a world and scenario that changes based on the player's choices.
