Well, considering the recent DS RPGs I've played it's a lot easier than the stuff out right now. Especially Hoshigami. I was expecting more rape in the form of horribly stacked battles, but not so much. The game seems downright easy compared to it.
That said, I'm very much enjoying the game. So far it's not very complex, but then I haven't progressed very far (Only a couple of hours in). The voices aren't great, but they're not terrible. They're a nice complement as opposed to voiceless battles (Leon's voice amuses me to no end. "Hey, cut it out, man!")
It doesn't stack up to FFT at all, but I'd say it's better than FFT:A. Simply put, it's a nice game. Nothing amazing or revolutionary, but nothing disastrous or leaving me questioning what science has done.
Jam it back in, in the dark.
