The worst puzzle in SH2 was the bug room. The other puzzles came down to finding the right item, but the bug room just left me guessing until I had to get help.
What I'm hoping for (and it looks like I won't be disappointed) is the ultra creepy atmosphere of SH1 and the SH2 Toluca Prison mixed with the strange, convoluted, but very well done story of SH2 for the whole game.
I hope the first Silent Hill movie is good, so they can move on to make at least 2 sequels. Seriously, though, this game looks GREAT. I can only hope the story (expanded apon) and gameplay are as good as they look to be.
