Radiant Historia
Radiant Historia: Perfect Chronology is a turn-based RPG from Atlus that first released on the Nintendo DS but then came as an updated port over to the 3DS just last year.
Time travel is a huge component in this game thanks to the main character taking hold of a special book called The White Chronicle. By using this tome, Stocke and his party can travel to different timelines and explore all of the branching paths that the book gives to you.
If you’re a completionist, you are going to want to see every single outcome that can happen, especially since seeing different outcomes can influence the game’s ending, which there are a few of.
Radiant Historia makes it very easy to see the different timelines and endings, as when something “bad” ends up happening, you can just jump back to the point where you made the decision and try again from there. You can also skip cutscenes and dialogue that you’ve already seen and your party members keep their experience points.
If time traveling appeals to you at all, then this DS-era RPG is a great pick.
