Finished the whole Ryza DX trilogy, what should I go for next?

I've been on a very lengthy JRPG spree for the last few months, and I originally dropped Ryza 1 because it was too easy (I later realized I needed to REALLY crank up the difficulty). Gave it another shot a few weeks ago, and now I've 100% all the way to the end of the trilogy.>!Kinda sad that Serri and Clifford didn't join us at the end, and we only got an episode for their shenanigans... even though she literally appears in the ending cutscene for some reason.!<

I could move onto another game, but with the Steam sale on full blast, and honestly a big hole in my heart for anything Atelier related at this point, I also never realized there were so many Atelier games. Begs the question of which ones I should go for, since I've seen Sophie 1-2 and Lydie & Suelle thrown about as the best ones.
