Why? Because it's 3rd person? So many people use that excuse but it's a silly one to use. Yes, they are very different games BUT the developers of Destiny were aiming for a FPSMMO. Regardless of whether or not people think Bungie succeeded in this, it is still the classification that Destiny is given. In many ways, they act very similarly. But people are quick to complain about Destiny because the general market for Destiny are used to normal First Person Shooters.
