Just got it today and i really like it. PC version the keys mapping is a bit awkward but i just use my 360 controller so its fine. Theres something about the lore and vigil's take on heaven and hell etc that i just love. I even bought the soundtrack which is epic.
As for Death's reasons for thinking War is innocent
According to wiki it is mentioned somewhere that out of the 4 horsemen War is the most honourable and his honour wouldn't allow him to bring the apocalypse early
I also love the makers, an interesting twist on Dwarfs, because thats what they are based on. I am just glad the PC version isn't as bugged as Darksiders 1 as that one had a few bugs that made it impossible to finish.
