Then you have completely missed the point. The story in destiny is just there to tie the game together. The game is really about the side quests. And those side quests could be infinitely added to.

Take Skyrim for instance. If you play ONLY the story missions back to back and do ZERO side quests, you cna complete it in under 10hrs. Some people speed ran the game in under 3hrs. When done you would probably end up with less than a 30% complete rating. However, if you do as much in the game as possible, you will be playing it for over 120hrs.

Vanilla Skyrim is pretty samey, though, but has a wide variety of quests, overall dungeon layouts, enemies, and objectives as well as a decent story that's interwoven with quests that branch into entirely seperate and complete story arcs. The map is mindnumbingly massive and repetitive after enough time but at least it has story to it that is entirely tangential to Dragons. Also modding.

Destiny doesn't really have any of this. Strike Missions do not build a narrative like the quests of Riven, defend X objective for the Yth time while Ghost monologues does not build a world like the Mage Guild quest line. Once the story is done, all you can do is grind guns and explore a handful of maps. This is Borderlands in Space.

that does'nt bother me,as I'm all about the multiplayer.

well theres only one raid at launch and even then its not aviable yet so even if he wanted to do it he cant

I didn't even know that game had a story, so that's a bonus for me

On Youtube a guy beat Destiny in 5 hours playing main story and PVP.

Here's the link. Watch at your discretion https://www.youtube.com/watch?v=Fnks1Xone24

Down the rabbit hole we go.

Destiny is advertised as RPG first. Not Halo.

Kind of expected, story is only a small part of the game. The real game is in all the PVP and PVE(multiplayer) modes so you can get better loot so you can continue to play those modes so you can get more loot.

That sounds quite short.
