Destiny - Why is it so addictive

So I have been mostly playing Destiny, for the last two or so months.  While I am not as experienced as some players, I do have two level 32s and a 31 who just needs some shards to reach level 32, ive completed Crota hard raid and every week I do three nightfalls, three raids and three weeklies.

So it is safe to say I have reached the end game.  Well until House of Wolves comes out later this year and ruins all my hard work so far!

By all rights, I should hate this game.  I dislike first person shooters, I despise first person shooters with death matches and I especially loathe people camping and shooting you with a sniper rifles from the other side of the map.

However I don't.  The key to this is the co-op mode.  Being able to play through the entire game with my friends is why I keep going back.

Actually playing the game has, in my eyes, several key stages.

Levels 1-20 - The training stage.  You play through the story, either alone or in a party.  In the grand scheme of things you are quite limited to what you can do, because you have only one sub class up to level 15 and gear is somewhat random.  You can (and should) actively do bounties at this stage as they give up a lot of exp compared to doing missions.  If you can stay ahead of the curve (1-2 levels above the recommended) then soloing is easy enough.  If you are in a party you can do most missions under levelled.

Levels 20-28  - The quest for legendary gear.  You are looking for your entry level legendary gear and some exotics. At this stage grab whatever armour exotics you can from Xur when he turns up if it is your class specific as that will help considerably with your level.  I was stuck at 26 for several weeks because I didn't understand how to progress.  The best way to get out of the slump here is to save up vanguard marks and just buy your armour.  Drops are very random and the key to getting better gear is to be able to compete in the higher level events.  

Levels 29-32 - The end game.  At this stage you can compete in the top end events. Raids, Nightfalls, 9 coin weeklies all should be competed in.  This give you the best rewards in the game, but you may find yourself casting off gear you only bought a few days/weeks ago to get you to this stage.

Throughout the game you can play pvp in various flavours as well.  The key is that there is always something to occupy your time with and a change to a different type of gaming.

At the moment I am trying to get better spec raid gear for my hunter so I can level it up to 32.  My Warlock is more or less complete and my Titan is done as much as I care to do on it.

Adeptus Mechanicus

The forthcoming release of Adeptus Mechanicus is something I have been waiting on for a long time.
They are the biggest faction in 40k to never really have a model range.  All the Forge World releases have been really exciting with the Horus Heresy range so it is good to see that they are finally doing a 40k version of this army.

From the sneak peeks it looks like they occupy a space around the eldar in terms of weapons and indeed in terms of statistics and points.  This could make them a very unusual imperial army.

The models themselves look solid.  Not forge world amazing but good.  I was hoping for some Johnny 5 type robots, or at least some tracked heavy weapons servitors, but nothing of that ilk seems to have been seen yet.

I plan on having a combined Ad mech and Knight army, but it is dependant on the codex options.
