What about the ending was a WTF moment for you?
I can't speak for Dac, but for me...
I think that 343 had the seeds of a good game, but they needed to spend more time fleshing out the story. I have
read all the novels, and I'm still not entirely clear on what the Prometheans are
I'm still missing terminals 1, 2, and 4 - those may explain it, though from the names I doubt it. Well, maybe Silentium
will answer the question.
It's definitely different
from the Bungie games. It veers further in the "space fantasy" direction than Bungie's games did. There's a lot
more cutscenes, it feels like. And I would have liked more callbacks to the old musical themes. But it's still a worthy successor overall.
