I'm about three hours in so far (just beat the first boss). I'm enjoying it enough, but so far I haven't really taken to the characters immediately like I did with Symphonia and especially Vesperia (I loved the hell out of Yuri). I like them enough, though, and Luke's such a damn prick I'm just looking forward to seeing his metamorphosis into someone who isn't a dick.
It's a shame that the 3D effects are almost nonexistent, though. I'm a big proponent of the 3DS' 3D effects in games that do a good job utilizing them (Super Mario 3D Land, Ridge Racer 3D, Ocarina of Time 3D, etc.), but this is the first 3DS game I've played where I feel playing with the 3D slider all the way off truly does make no difference. Seriously, the "3D" is so botched in this port that there's hardly any difference between having the 3D slider all the way on versus just turned off.
But, oh well. That's ultimately a fairly minor quibble, as the game itself is still fun. I just hope the story ramps up and gets going fairly soon!
