For the moment the game is absolutely incompatible with any version of the XB1 wireless controllers. Steam is blowing up because of this. Wired controllers and Xbox 360 wireless controllers work fine. This was a big miss on the developers side, as the Unity engine is known to not play nice with the XB1 controller. This game needs every sale, and all the good feedback it can possibly get, and Tokyo RPG Factory shot themselves in the foot with this oversight. Until I gain the determination to scrounge through my garage looking through boxes for my Xbox 360 controller, I've been demoted to watching my friend play the first couple hours. The keyboard and mouse controls work fine, but that just isn't my scene, baby.
Moving on, the game looks beautiful, and the piano music and prevalent snowfall give it a melancholy feeling. This image does a nice job capturing the feel of the game:
I Am Setsuna feels like a 3DS RPG, but with superior graphics and sound. What I mean by that is the world feels small, at times claustrophobic. But that fits in nicely with the mood of the game. Like most 3DS RPGs, the combat is easy, but there is a good amount of depth to the mechanics. I've read that the boss battles offer a good challenge, but this early in the game I haven't been able to confirm that. After playing Dark Souls and Pillars of Eternity on hard mode, I Am Setsuna is a nice, relaxing change of pace.
Recommended if you like JRPGs.
