Greed. Trying to make this a PvP game like CoD and Battlefield. Doesn't cost them money once a map is in place, but having to put out real PvE content costs money. Greed. Chopping the game up and selling it in pieces. Greed. Making people RE-BUY the taken king on xbox one so they could play rise of iron. I still see no difference in the 360 and xbox one versions of destiny. Greed. Cutting costs using p2p instead of dedicated servers.
