Sometimes 3D looks too much like real humans, which actually loses its dreamy feel and isn't cool enough. I rarely choose 3D unless I'm not playing this game to date and have handsome men.
I can accept both 2D and 3D, but I prefer 2D. Sometimes 3D character movements are too much and can make the plot feel dragged out. I absolutely can't let go of 2D illustrations—they're just too beautiful.
