I've only played 1 and 2 so far. I like 1 more overall but there is certainly a reason that 2 is a classic. The atmosphere in that one is second to none and the story is very good.
Not at all excited for the remake though. It looks like it misses the tone of the original. The original is so steeped in symbolism so its weird to see a new dev team that wouldn't have the same understanding of the symbols as the original dev team make it.
