@ares42: If you aren't playing online, you're only getting the worst parts of the experience in my opinion. I'm not sure if you're getting the Journey-like random player encounters without Plus, but that really adds a lot to the open world exploration for me. The Strike missions are fucking great; they almost perfectly blend traditional MMO dungeon/RPG design with Halo coop missions. All of this comes together in the multiplayer mode where you bring back all your favourite looted guns for competitive play (your loot acquisition in multiplayer is pretty lackluster--you're encouraged to scavenge the world for new gear). For me, the most impressive thing about the game is that it harmoniously brings all these things together--something that you apparently feel the opposite about.
@wemibelec90: I completely agree. I wish they spent more time introducing each of the enemy factions as distinct entities. It feels like they've set up a fantastic backstory and 'background lore,' but struggle materializing it for players to enjoy. I understand that they want to keep swapping around enemies for variety's sake, but they use The Hive and The Fallen almost interchangeably in early missions. If it weren't for a couple three-way conflicts, I would have thought that they were allies.
In Bungie's defence, these early portions of the game aren't trying to tackle lofty, heavy narrative beats. Your character is just trying to survive and establish a rudimentary infrastructure for the rest of the journey. It isn't that they're trying and failing, it's that they aren't trying to begin with. They desperately need a bit more of a narrative hook in this prologue experience, then they can briefly wander back into this infrastructure business.
