Got Xenoblade Chronicles 3D today and so far it's going well, though it's clear where the hits were taken to make this work on the 3DS. Not that I played the original and have a comparison, just going on its own merits. Performance, it's been running smooth, though slow down in the first Metal Face fight. Textures are where things go bad. Not everything looks bad, but faces look awful. Like maybe above PS1 quality at best. That and just overall crispness is what took the biggest hit for sure I feel. Which I'm fine with, I'd rather the game play better than look better.
Another odd thing is that they didn't seem to have implemented ANY touch controls. Not even for menu's or anything. After using it so much in Majora's Mask and recently Animal Crossing, I had to keep myself from reaching for the stick a few times, thinking I needed it for the menu's lol I guess it's not a bad thing in particular as I don't require touch controls in my games, I just thought it was a bit surprising to not find here.
Game itself is cool though. Sure to enjoy this.
