I've never heard Destiny summed up better than:
"We were going to say that Bungie had made no effort at all in any aspect of the game, but that’s not quite true. In terms of taking ruthless advantage of their fans they’ve left no corner unturned."

....the game’s easily tricked artificial intelligence. In fact we’d swear it’s actually got worse since we last played it, as more than once we caught bad guys just standing completely still, staring forlornly into the middle distance – which we can totally understand given the game, but if we have to make the effort at least they could too.
