Thus far I'm very happy with the game. I'm inside the ship right now, finished placing the bombs. I don't really know how anyone could have had time to finish the entire game by now, but I guess I don't have as much time to play as I thought lol.
I was already set up for the idea that little, if anything, was going to be fully answered in this title and that most of it would wind up in the second half. Even considering this, I'm finding the game interesting and I am enjoying the characters, particularly Argilla. I don't really mind the role of a girl who has some power that will save everyone or whatever else. It's done well and in a convincing manner. I, personally, am completely burned out on anime in general and the general themes, but something like that has appeared since the dawn of storytelling. I can't really fault it if it is approached well and other things make up for it.
I also enjoy the little things in the game that are not majorly important, but might be worth reading into elsewhere to find out more about them. Nocturne had a lot of this thanks to its references. DDS has far less, but there are still a lot of interesting religious-type references that I've been reading about. Chakras, for example, and how the different Tribes' sectors are named after them. It's mostly small things, but I enjoy that aspect of MegaTen in general.
As for the gameplay, I like it. The Mantra system is a nice middle ground after what was done in Nocturne. Actually being able to choose your skills and set them as needed can be a godsend at times. Maybe I've not reached any major battles yet, but I've not had any deaths thanks to bosses thus far with the way I have my characters set up.
I was a bit annoyed by the reused enemy models, but there are quite a bit of new ones as well. In the scheme of things, it really didn't affect much. The battles were still engaging and entertaining. In fact, I think I've used the Auto mode in this title far less than in Nocturne for several different reasons. A lot of the time it's just not in my best interest to use the same attacks over and over for some of the battles.
So I don't know, even so far I feel I've gotten my money's worth. I don't care that the story won't be completely resolved because there's so much to do in the game otherwise. Considering some of the other stuff I could be wasting that money on software-wise, I'm content. There's as much to do in these games than anything anyone would be willing to spend $50 on otherwise, so I can't really expect to pay $30 apiece for these things.
