@devise22: I feel like the problem is that Destiny does many things that other games do, but just not as well. Your comparisons seem confusing. Why would I compare Destiny's story to Terraria, Minecraft, Cod, or Battlefield. I play Terraria and Minecraft because I know it will give me a endless experience of building whatever I want. I play Cod and Battlefield for the Multiplayer. People buy certain games with expectations of what they will be based on marketing, early beta impressions (in this games case), and the company's prior game library.
I don't think it's far fetched to say that people expected a story as good as, or at least close to Halo. Multiplayer similar to or as good as Halo. I understand they are trying to make a completely different IP and that's fine, but damn this game feels like it is trying to be Halo. It's Sci-Fi, the Hive sounds like the flood, and the robot bad guys sound like the Convent in the story. The movement feels the same, and the combat. The enemies have religious undertones.
The loot system feels pointless, and not even by comparison to Diablo or Borderlands. Not getting enough loot isn't an issue, since in Diablo and Borderlands you'd get so much loot that 90% of it was garbage. It just seems like they didn't even need to put in the loot system to begin with, or leveling for that matter. The exploration system is nothing like Skyrim. Yes people will grind away in MMOs, but with thousands of other players, which seemingly endless things to do. I know some would argue that the story in some MMOS are insanely fleshed out and detailed. You could read for days just playing World of Warcraft or The Old Republic. Which really immerses you in the world.
