Bungie does the bait and switch again. You can't call it an expansion because they strip away about as much as they introduce, which is a big problem, because I am not a fan of the drastic changes to the mod systems, but even if you did not buy Lightfall, you're free to play or previous versions are forced to take the new update. The new location and characters are hideous, like a half hearted attempt to jump on the cyber punk bandwagon. The expansion in it's entirety feels like it is considerably lacking in the polish you would expect for a $60 expansion
