Just finished off
Ys Seven. Given that I've played through most of the series now (in some cases multiple versions of the same games), I think I'd have to say that this one is definitely my favorite. The combat system in it is nice and fluid, with the Evade button adding a level of skill to the combat aside from just standing around hacking at enemies. There's also a block ability, but timing it to the incoming attacks can be a pain, especially considering it requires pressing both shoulder buttons to utilize. I generally found it easier to dash around to evade stuff, since that just requires a single button press and a directional input.
Some of the boss fights were hectic, with plenty of stuff to avoid while trying to get some hits in.
Overall, the game brought back memories of my first play through
Secret of Mana back when it released. It is definitely an action RPG, much akin to
SoM, but faster paced combat. The music is rather decent, and reminds me of the TG-CD releases in some cases... which generally seem to hold fairly high marks across the board. I found that graphically, the game looked nicer than the PS2 release of the previous entry in the series
Ark of Napishtim. This is even considering the fact that I was playing it on an HDTV via the official component cable, which was then stretched to fill the full screen by an XRGB-mini. The character and monster models just seemed to be designed much better this time around.
If there's one bad-ish thing to say about it, it would have to be the story, somewhat. Granted, I've seen much, much worse... but overall, it kind of seemed like some kind of bastard offspring of
Captain Planet +
The Matrix. I'll just leave it at that, to leave some speculation for those who haven't played it yet.

In any case, it was enjoyable to play, which matters more to me than the story.
Edit: One thing I forgot to mention... the 4 characters you have in reserve do still gain experience even when you aren't using them. This is nice since you don't have to worry about switching them out to keep everyone at relatively the same power level for those times when you want/need to switch them up. Their combat skills won't level if they aren't used, but it's not like they're worthless at lower levels or anything.
