in late 2013 and earlier 2014, age range testing for the game began and activision figured out that younger children and those who dont care to think critically in a video game didnt appeal to the expansive world they created. Younger kids just want to shoot aliens and watch their face blow up... many other planets and moons/satellites, and generally the worlds we are playing on now were once anywhere from 5 to 10x's larger than the size they are currently.
After finding out that people will not exactly "throw money" at their game as often as they would prefer, they forced the person (good friend of mine) who created the Destiny universe to re-write the story onto grim'pokemon cards, cut over 75% of the original content this game was suppose to have and began focusing on a quarterly DLC agenda.
Then Destiny hit the shelves, Joe Staten left the company and the game itself was reviewed in general around the 6/10, 7/10 ratings.
And the kids and morons are now throwing money at the screen cause destiny herpa derpa destiny.
