To begin, I love ARR. It is by far my favorite game in existence. I began as a 1.0 player and unfortunately had missed gaining legacy status by only a few short weeks. When I first set foot in Eorzea during 1.0, I fell in love. Yes 1.0 was lacking many things but they did one thing right that most major MMOs still seem to leave out. What I am speaking of is realistic running animation.
I don't mean just the look of sprinting though. In 1.0 (for those that didn't play or have never seen it played) you leaned into turns and your character could not stop on a dime like they do now. It gave your movement weight and that is a feeling no other MMO ever really has had. It is something so little, but I can't even explain with words how awesome that feature was, and I know I am not alone in this thought. . Not only did you lean though. if you were sprinting and tried to stop, you would slide a little. Something so simple as this added so much to the atmosphere of the game!
