Here lies some gameplay footage of Heavy Rain's Demo taken from Games Com: 
 
 

I'm fucking sold. Dare I say David Cage has done it?

It's a shame about the sound quality, but even despite that I can easily hear that it's got better voice work than I've seen before in earlier gameplay, a lot better in fact. 
 
It certainly looks like a strong contender, but of course it is coming in early 2010, as many other big games are also.

Saw this video earlier on Gametrailers, its pretty sweet i must say.

" The more I see this game, the more I want it. I'm gonna predict this game is my GOTY of 2010 actually how good it looks. "

Those look great.
 
Thanks dcpc10.

" @get2sammyb: David Cage is a master developer. We will be talking about this game for years to come.  "

Well well, the voice acting here seems much more promising than that ol' junkyard scene.

Now that looks like a game I could get excited about. When I saw those trailers a few months ago I was not sold at all. This looks promising though.

hmmm you know along with Alan Wake I hope this game makes it but man it just looks weird I am not sure...

I wasn't too excited about this one.....until I saw those videos.....now.....wow......

Even if the game isn't finished, it looks absolutely amazing.

Sold!

This game looks great. If it's reviewed well, I'll definitely pick it up.

Is this going to be 2010's Mirror's Edge?

Looks great. That is a ballsy cashier.

Another outcome for the scene!

Let's build a time machine and show that to the people in 1985. It'll be awesome.

Impressive. Never really thought much about this but since I'm getting a PS3 sometime soon I'll definetly look out for this one.

This is the trailer that sold me..
 

 I like how they've incorporated the on-screen button commands, transparently.  Also the floating commands add a sense of tension. Very cool. :D

that looked sick

" @trophyhunter: Did you seriously just compare an Atari game to a Remedy game? These are the people behind Max Payne and it has nothing in common with Alone in the Dark other than the 3rd Person perspective. Alan Wake is even going to have an open world for free roaming for crying out loud.  But anyways GREAT GAMEPLAY VIDS! I absolutely loved Indigo Prophecy and this one looks even better, the impact of choices in these games is awesome. Can't wait! "

This game makes me want to get a PS3.

Looks like this showed some of the better end of the voice cast....

This game looks so amazing. I really think what they're showing off with this is pretty incredible. I can't wait for it to come out. Definitely an early GOTY contender for 2010.

Check out Ethan's Japanese voice on the Japanese website:

Game keeps looking better and better. I can tell in these situations, for the first time really in a game the player can actually feel worried about what may happen, and seriously try to be careful while playing so they don't die. You can definitely feel the tension just by watching the video, I can't wait till Heavy Rain comes out. This an Alan Wake.

I am now sold on this game.
