I just picked up the limited edition at Gamestop, because they still had a copy. They put the soundtrack CD into the box, and forgot to put the game in. I am finally playing it now.
I haven't read the first 10 pages out of fear of spoilers, but I'll say that the lore for the secondary weapons and things is pretty interesting. The whole game reeks of quality production.
Lament of Innocence nailed the exp system, RPG-lite inventory be damned. Nothing compliments bloodlust better than getting experience points for slaughtering hordes. I see that I can replay levels in this game, but a buddy said that leveling up doesn't make the game easier, but screw him. I want to blood come out and numbers go up!
