I started Atelier Totori, I like it, but I don't like that its time based, and you need to get a certain amount of points to move forward. Dragons Crown is really fun, it's mostly a co-op game so its a lot more fun if you have friends to play it with online.
other Atlus games I have Played Persona 2, 3, and 4, Shin Megami Tensei 4 on 3DS, Etrian Odyssey , Code of Princess, Stella Deus, Odin Sphere, Persona 4 Arena, Crimsom Gem Saga, Catherine
