This isnt an MMO. 12 ppl at any one time is the most that can be seen. Thats not massive. Destiny Is a shooter game made by a company that heard about what an MMO was and without doing any research tried jamming MMO style of loot into a shooter. Yes there should be some sort of buy back, but sadly they have decided not to do such a thing. http://www.bungie.net/en/Help/Article/12211
