I'm with Phi on Dawn of Sarrow. To me it didn't wasn't as good as Aria and the use of the touchscreen felt really gimmicky, which is why I'm contemplating on selling it. Plus, im my opinion, I felt most of the souls and items in Dawn were weak compared to Aria. (I miss the Red Minotaur soul, it was stupid powerful.)
I do have Order of Ecclesia but not Portrait of Ruin though. Ecclesia is much more challenging than Dawn (especially Lv.1 Hard Mode on a clean save) and more enjoyable.
