I noted something interesting in Fable 3. They had player spheres which you could see if you opted into it. These spheres were everywhere in the world maps of Albion moving around because these were players on a shared server and you could trade items and gift other players or join their experience as a Henchman. Now if the player could turn this feature on and off in Fable then they could do it individually in Destiny to avoid combative players looking for lulz.
