The same system that gave us these?
Sorry, but I've owned a 3DS since launch and I expected much more from the graphics. The overworld in particular is something you'd see on the DS. The battles aren't much either, the effects look lazy and the models are plain looking and lack charisma. The backgrounds especially are ugly.
3D has always been hit or miss, and we are way past the days when they're still something completely mindblowing. 2D always managed to look timeless...but Pokemon X/Y right now looks dated already. I get what they're trying to get with the artstyle, but it's not fit for 3D at all.
