Fahrenheit is quite an old game, but after seeing the QL, I'm kinda interested in it. Does it still hold up today, or has it aged too badly?

Yes I certainly think it is.

 
You enjoying the quicklook should be a good enough reason. The 'aging' was visible in it.

Yeah, the gameplay hasn't really aged because well... to be frank, there isn't really any. It's more of an experience. 

In my opinion, it isn't worth getting because of the really dumb turn the plot takes halfway through and the forced romantic interest it gets into. It goes reeeeeally off message and lost most of its appeal at that point.
If it's gonna be an interactive movie, then at least have the movie be better than a b-movie.

yep

I bought it just today, so yeah, I definitely think it's worth getting.

If it was regarded as a good game at one time and you think you're interested in playing it then I would say its definitely worth playing.  I recently started playing through KOTOR because I've heard its an amazing game.  Just because they are old now doesn't mean its not worth playing, just have to look past some of the faults because developers didn't know what they know now about games.

The concept of the game is interesting enough, but the gameplay is for most part horrible, so most people will just get bored after a while.  And there are some details misconceived.
 
So no.

Just make sure you stop playing halfway through...
 
When the game becomes Dragonball or Matrix, it ruins everything they build up in the first half. And the ending is just a big mess.

I absolutely loved the game, when I played it at release.
 
The recent QuickLook just kind of made me want to play ti again, in anticipation of Heavy Rain.

The supernatural twist was not so great but I still say it was worth while. Indigo has decisions with lasting consequences and the quick time events can actually be pretty intense. Running down a hallway with things coming at you left and right, just barely getting the button presses in time, It actually feels quite rewarding . The game is just different. If the quick look got you interested then I'd definitely go for it.

You can download it or buy it so cheap its worth getting even as a curiosity at this point.

If you like the look of it then go for it. Other people's experiences of games aren't your experiences, so if you think you'd like it - why not? Doesn't matter if it's older. You might notice one or two things but if you like the game then you'll forgive that anyway. 
 
Just make sure you're up for some multi-tasking in places (I could never do any parts that involved having to control breathing while doing some other task. It was hard enough to focus on the one!).

Yeah. It's cheap now. Just get through 2/3 of the game, leave, and don't finish it.  You will be dissappointed.

Indigo Prophecy is probably good if you're interested in Heavy Rain or had your interest piqued by the quick look.  It at least gives you a point of reference as to what Quantic Dream is trying to accomplish (and as everyone else mentions how it can go so terribly wrong).  When you hear David Cage talk about learning his lessons from Indigo Prophecy/Fahrenheit you need to hit the second part of the game to understand what lessons he's talking about because that game goes completely off it's rails.

Not everyone agrees, but I'd say that the consensus is yes? I really liked the story stuff I saw in the QL, and to hear that it goes mental after a while is kinda disappointing, but I feel that I should play this game. So I'll pick it up. Thanks for the help guys.

Everyone who has never played this game but watched the quick look:
 
You watched the best part of the game.  It gets steadily worse from there.  The quick time events near the end of the game are some of the worst gameplay I have ever played (that fight scene on the top of the building was literally a huge physical test and one of the most terrible moments I've ever played through in gaming, I mean HOW THE FUCK DID THIS SEEM LIKE A GOOD IDEA AND MAKE IT IN THE GAME!?!) and the story gets much more outlandish and nonsensical from there, and not in any sort of good way.  Don't think it's just going to be like what you watched, you will be disappointed.  Enjoy the ideas in the quicklook and wait for Heavy Rain instead, it looks like Quantic Dream figured out everything they did wrong. 
 
 Indigo Prophesy is an intersting game, but really isn't a good one.
 
 
 
EDIT:  I hadn't looked at the poll numbers.  I really can't believe people who voted yes played through the game.  It's really not very good.

Yes, it's absolutely worth it. While it's true that it takes a wrong turn about halfway through (no spoilers but believe the hype: its dumb), you should be able to find it for dirt cheap and its one of those games that everyone should experience at least once for it being such a bold piece of design.

Don't do it.
If you play indigo prophecy (which becomes worse and worse the longer you play it), you will become less excited for Heavy Rain, which looks awesome.
 
Also, I totally agree with the guy above. You allready watched the best part of the game, literally, that is the most fun/exciting/interesting the game will be for the entirety of the time you play it, and even that won't be that exciting because you've seen it before.

It's a pretty unique game, so you should at least try it out just to understand what Heavy Rain might be like. 
 
I just love how mundane the game tries to be. I know that's like saying games shouldn't be about blockbuster explosions, but with the Psychology meter, it's always interesting. Tyler has a cup of coffee, and he is +5 less anxious.

If you enjoyed watching the Quick Look, then you'll enjoy playing the game.

I am playing through it for the second time, i played it when it first came out  about 4 years ago. 
There are some really frustrating moments in the game. but saying that I have a lot of good memories  
about my first play through so I think its worth it. 

@ianmac:

I bought it on Steam and finished it since the QL. Except for the tank movement controls, I really enjoyed it. It is definitely a very unique game. I was surprised that QTE stuff isn't actually the majority of the game. The walking around and interacting with the environment gameplay plays a bigger role. I only failed one of the QTEs so I didn't think they were that bad. The worst parts are probably the flashbacks and one really big plot hole that's bothering me. I recommend it if you have money to spare.

I just noticed it's on sale on Steam right now for $3.39, so if you're interested in it in the slightest, you probably wouldn't be too let down even if you don't like the game, after all.

why would it not be

Yes it is.
