The Atelier Arland trilogy Rorona, Totori and then Meruru in chronological order assuming they were released in english on Switch. They're just ports of the Plus versions that were previously on Vita (the base PS3 game + all the DLCs included by default, Rorona Plus was pretty much a remake on the other hand).
Lydie&Suelle is the third installment of the Mysterious trilogy which is incredibly dull in comparison of Arland, alongside of the typical KT/Gust jewry with the DLCs (such as synthesized items like the upgraded bag to gather items). There's also the problem Gust went on three different projects at once between Blue Reflection, Nights of Azure 2 and the Ateliers
