Il gioco ne tiene conto in realtà, anche se per diverse cose (spoiler free).
- Don't do the Part 1 playthroughs in parallel, like what the YouTuber SkillUp did in his 30-hour preview. Turns out, there are these things called Global values that are only carried over AFTER you have finished 1 route.
- Specifically, the things that carry over are your World Map / Dungeon progress, non-unique sidequest completion progress, and a few other things.
- If you don't want to do the boring non-unique stuff over and over, it's recommended to finish each of the Part 1 campaigns one by one.
- EDIT: Another reason not to do the Part 1 arcs in parallel, is because a huge amount of your achievement points (Karma Shards) to unlock Boons of Salvation bonuses is tied to the completion of each Part 1. These Karma Shards are what you use to unlock 30% / 50% bonus EXP, etc. Once unlocked, these bonuses are all toggles that you can turn on or off.
