Well, as far as story goes, it's a little more simplistic than those three, but it's just way more fun to play than those three. The Factory minigame is quite possibly the most difficult one to figure out that I've ever played. I've made it all the way to Vedan, so far.
The art style is awesome (cutscenes are fuckin' awesome), but at the same time, having it cel-shaded detracts from the story just a little bit. There are some story bits that I can see what the devs wanted us to feel (happy, sad, betrayed), but the way some of the characters who say those lines look creates this odd juxtaposition that glares at me everytime I see it.
For all who care to know, one of my top three RPG's (haven't finished it yet, but that's where it stands right now), and definitely in one of the top 20 games I've ever played.
