Well, I've completed Destiny . And I have to say I really enjoyed it once I left the Earth level, which as the openning arena was very bland and so like many other games that it was a bit of a disappointment. BUT once I got to the Moon and Mars I really got into it, as the environments and enemies were far better ,though having improved weaponary and armour helps. That also translated over into the Crucible, my rifle which is maxed out now seems to have considerably more accuracy and power, but again that may be due to the fact I'm now used to it. I'm finishing middle of the pack now, but I cannot compete with the reflexes of people probably decades younger. It comes down to a fraction of a second but I'm still getting wacked and double kills, both me and the enemy at the same time are quite common.
Its a shame every mission returns to the same starting point on each planet, that makes the storyline feel repetitive as opposed to the smooth progression in Halo, and it is a slow build to get to a "Masterchief" level of invincibility, but it was worth it in the end. Still can't find all the golden cheats but above a certain level they seem pretty pointless anyway. Don't know how much more play I'll get out of it, these multiplayer on lines might be alright for those who like to endlessly duel or run tactical battles but I preffer an immersive story that takes me out of the world for a while. Role on Halo and I might upgrade to an Xbox One for that.
