I finished the Woodpalna/Rexwood part. As I was going through the eastern tower dungeon, it hit me that I'm actually playing a remake of DQ7. I know that's weird, but I never actually thought it would ever be done, because it's such a massive game.
So far, everything is intact except for the trial dungeon, and hopefully it remains that way. The orchestrated music is great, the game looks pretty nice too - as good as DQ5 PS2 in most aspects, and better as far as character models and lighting go. Battles are still really fast, and the over-the-shoulder perspective in battle is a good change. Dungeons seem pretty much the same in terms of layout for the most part (which I consider to be a good thing), although the graphics are obviously improved quite a bit, and the puzzles in the colorstone mine were slightly different. There also seems to be even more party chat, as I expected. Maribel in particular has a fair bit more to say than she did in the original version.
One of the neatest additions, in my opinion, is the "past adventures" option in the menu, which gives a great description of each even that's happened so far. There's also a "recent adventures" option that says what happened most recently, which serves as a good reminder if you happened to put the game down for a while or something. Of course, also in that menu is the "next shard" option which will tell you if there's any shards in areas you can currently access. Along with that is a shard list, which lets you view every shard you've collected, with a little note saying where you got it. All very useful stuff.
So far, I'm very satisfied. This is the kind of treatment DQ6 deserved, but I'm glad that DQ7 got it at least.
