I'll be interested to hear your impressions. This game has been on my radar for a while, but it seems way different from anything I've played before, so I'm a bit reserved about it.
It is pretty different from your standard adventure game. It's supposed to be a cinematic experience. . . So, really, you just control your character as they go through a scripted movie. You have decisions to make that cause the movie to go down paths. It's a lot of pressing X or triangle. Or moving your joy stick in different patterns. They can actually get pretty complicated.
And it's very puzzle-like. You have to like puzzle games. The puzzles aren't really hard, but you have to do certain things in order to trigger certain events. You also really have to pay attention to what's going on. Be very observant. Pay attention to anything that can be a clue (the colour of ppl's hair, their clothes, cars, etc). And also, when things start to happen (and you know when they do), don't take your eyes off the T.V., 'cos if you do, you might miss the fact that you were supposed to press a button and now you're lying flat on your ass. (That actually hasn't happened, but it's that sort of thing)
I'm really liking it so far. It's gotten a little scary at times too. (Though, I'll admit, I'm a huge wuss.) Graphics are awesome. Storyline is pretty damn interesting.
Like I said, I was a big fan of Indigo Prophecy (Or Farenheit as it was known in Europe), so I knew what to expect going into this game. If you don't wanna shell out the cash for it yet (I bought it used, and with tax it still cost me $61 CAD), and you can find it, try out Indigo Prophecy. I played it on original Xbox, but it's also for PC and you can download it. There are two versions of it. The North American and the European. The European is uncut, but the North American one had an interactive sex scene removed. (Though, in Heavy Rain, there's boobies and bums. And shower scenes. I was pretty surprised, actually.) Apparently, you can now get the "director's cut", on-line.
