Destiny, the flagship title from the studio behind Halo, is the most expensive game ever, costing over $500 million to produce. The most expensive film ever made, Spiderman 3, cost $258 million. While a large proportion of that money has gone into marketing and hype, Destiny is remarkably innovative for a number of reasons. The story, the sandbox worlds, and playing with strangers meld seamlessly into one. You can suddenly find yourself engaging in a strike mission with strangers, who then take you to some other planet you’ve never been before. So the benefits for cooperation are potentially huge. The worlds themselves are colossal, as well as stunningly designed. The game is going to be expanded regularly, with a story that is supposed to respond to the way people play the game.
