That’s a tough question. Nalthis would be cool - technically, anyone there can Awaken as well, as long as you accumulate enough Breaths, which also give you cool passive bonuses. But also I want to see magic powered spaceships, and we don’t have enough books set in late eras yet.
For me, Elden Ring. I enjoy open world exploration and collecting-heavy games, and I also enjoy soulslikes for the strategic combat and variety of options. So ER was like two of my favorite ice cream flavors combined into one delicious meal.
