With Dawn of Sorrow, grinding was never a problem for me... Soul Eater Ring + Three 7s + Maxed out Ghost Dancer soul (didn't even bother with Dead Warrior) = souls dropping like crazy... I got all the souls, and all the weapons, and if I had to sacrifice boss souls to prevent me getting the Chaos Ring, the story (when you're equipped with Claimh Solais and Valmanway) is able to be beaten in 3 hours, to where you can nab all the boss souls because they're automatic drops... My only problems with Dawn of Sorrow is that the story is mediocre, the souls aren't as good as they were in Aria, and the game is too easy, even on Hard Mode... Tho I am enjoying Julius Mode, as it's a really nice challenge... I don't have a problem with the castle layout... heck, my favorite area of the castle is the Demon Guest House, because there was obviously a lot of thought put into it's rooms... yeah, it's suffers from copy and paste, but with certain enemy placement, every room is different, and looking at the map design, it looks and feels like a little apartment complex within the castle, and it works because that's what it is... as for what I like better, the GBA or the DS games, I feel both are a mixed bag... I haven't gotten around to Portrait or Order yet, but I can't wait to play them because they seem to offer a variety in the gameplay... I didn't really Harmony, as the music and castle design threw me off, I really enjoyed Aria, and right now I'm playing Circle... and my favorite is Circle, just because it offers a fun challenge, and is more challenging than the other metroidvania handhelds...
