The voice acting brings in some amazing talent, particularly Nathan Fillion's hilarious character--Cayde-6. Unfortunately, some of the other bits of voice acting fall flat or sound too cartoonish in comparison. Still, I'm willing to play through the campaign again just to hear some of Fillion's dialogue.
Sadly, the story does not hold to as high of a grade. It's serviceable, but predictable. This is true for the main plot as well as the side quests. I suppose that there is not much room for subtlety in a shoot-em-up game, but as this most reminds me of the Borderlands series of games, it did not fare as well in comparison.
The other element holding it back from greatness is the confusing menu, crafting, and quest systems. Even getting through the main campaign, I am still confused about a variety of areas that should be more straightforward. I'm hoping that they will become clearer as I continue to play in the substantial amount of endgame content.
