My DSFire card broke because of a horrible sink mishap, so I only have 3 DS games to play now. Luckily, they're all pretty good.
Ecclesia is pretty fun. I'm a huge fan of Castletroid games, and this one is a bit of an expansion on the theme. It's more like Castlevania 2, in that you're traveling to a bunch of smaller zones. At first it seems really easy, (except the bosses, which are excruciating,) but things ramp up pretty well once you get to the main castle. I'm really obsessive about collecting in these games, and collecting is less of a chore here because it seems that they increased your odds of finding rare treasure drops and glyphs. I don't mind the glyph system, but it seems like I'm sticking with two sets of glyphs for most of the game. I'm almost done with it, so I might post something about the whole thing afterward.
I'm also playing the Final Fantasy 4 remake, which is pretty much exactly what I expected. There is one thing that was kind of annoying to me, and I don't remember if this was in the SNES or GBA versions, since it's been so long since I've played either. When Cecil becomes a paladin on Mt. Ordeals, the game drops his level all the way back down to 1. This means that all the time you spend grinding him before this is just wasted. It's a small thing, but it was a little discouraging. Oh, and the voice work is surprisingly good for a Square game.
Lastly, I'm finally getting around to play Phantom Hourglass, which is blowing me away. Of course Nintendo is going to find the best way to use their own hardware, but the controls are so intuitive that I didn't realize until about halfway through the game that I wasn't using any of the face buttons, save bringing up my map every so often. I love this game so much that I almost don't want to beat it.
