I recently played through some of the PS2 version. I had the original for gamecube, I see a large improvement over the two. I was just disappointed out how often the chain weapon was used. It felt like there was two many instances of pull said gaurds into item until it is destroyed.
I played the demo.. and it seems a little different from the first, but I can't quite put my finger on it.. though I can say that it just seemed like a typical mediocre action/adventure console game that tries a little too hard with the sarcasm(a lot more than the first) and to be "cool". It just seems too cheesy. I'd much rather spend my time checking out the new Vampire The Masquerade.
