It is obvious by your moments and your characters that you play with no consistency. Of course it will be enough for you because you play periodically. Hell Candy Crush probably has enough content and that is free. Destiny offers around 30 hours of actual new content. The rest is grinding which does not equal content. That's fine you enjoy the game but the reality is it is lacking in many areas. It might suit your occasional play time but nearly every game invented probably would and there have been plenty of shitty games.
