The one way I thought Okami could be better was if it had the same art style with much better graphics, for instance if it was on PS3, but this has gone the opposite way :(
Call of Juarez is one of my favourite games, a really underrated western classic. I personally loved the Billy stealth elements just as much as Ray's hell and damnation bloodshed. I thought the two elements combined really well to create a tension and release experience where after spending a long time sneaking past the bad guys, you got to blow their heads off.
