Done with Order of Ecclesia, which I found to be the most challenging of the GBA/DS games by far. Difficulty aside, though, I didn't end up digging it as much as I thought I would. Shanoa's design is cool, but I think her kit is lackluster compared with Jonathan/Charlotte or Soma. Most of her weapon glyphs have the same basic range and arc, with their main functional difference just being damage type, so they don't really feel distinct from one another. I like the move back to having separate levels instead of just the one large castle map, but it feels like a wasted opportunity when their design is so bland and repetitive...a few of them are just entirely flat zones where you fight the same 2 or 3 enemies over and over. On the plus side, it does have one of the better CV stories, and some of the bosses are really cool.
My ranking of the two collections:
1) Aria of Sorrow
2) Portrait of Ruin
3) Circle of the Moon
4) Order of Ecclesia
5) Dawn of Sorrow
6) Harmony of Dissonance
