The standard to which all other online shared world shooters are held for the feel of gunplay, physics, and character movement.
The story is engaging, but can be hit and miss from season to season. When you do have a goodly chunk of story content to chew through, it feels like it doesn't last quite long enough. However, that may be because the story beats during those times have a way of holding you in your seat until you are DONE.
Can't recommend enough as a FTP, or (even better) a season pass purchase to support Bungie and the continued development of the game and world.
