I also loved FFXIII, although I didn't much care for Snow, haha. He needed to calm down and learn not to try and tackle Barthandelus, it never worked. I mainly loved it for the gameplay, visuals, music, and pacing. And by gameplay I mean mainly the combat system. I love the battles in XIII SO much.
And FFX is my favorite game of all time, screw the haters. I love that game with an unhealthy passion.
