Different installments in Gust’s Atelier series can find themselves known for different things. Atelier Firis was about getting more places to go. Atelier Sophie tries to make people realize why each recipe mattered. With Atelier Lulua: The Scion of Arland, it can feel like the theme is efficiency. That extends to alchemy, exploring a world, telling a story and offering an epilogue to one of the better known Atelier trilogies.
