At this time a character is comprised of many elements that are taken from the DC Universe. And although the costume editor will not be as massive as CoH or CO a characters look will easily be iconic "DC" in appearance and will reflect their origin as well. A great deal of gear that you earn in game will reflect your game progress and achievements but still stay with in your origin theme and personal colors, or even invisible to those who wish to keep their character simple.
Some game elements that they will be looking at are yearly events, such as the Brainiac invasion, also the big DC events will be brought into the game about a year after they are published in the comics.
Those concerned about being ganked, by a bunch of villains in a PvP situation in the open wold will be comforted that is a someone gets repeatedly killed by an overwhelming force it summons the JLA or LoD to come stomp the griefers
