So yeah, I'm really thinking about buying a PS3 just to play this game. Last month, I bought Indigo Prophecy on Steam, played it, and, like most, enjoyed the story and what the game was trying to do, more than how it actually executed it (making a sort of interactive story thing, rather than a traditional video game). 
 
I'm a huge fan of storytelling through videogames, and this game looks like pretty much everything I want in a story-centric game right now. Is it bad that there's a very good chance that I'm going to buy a PS3 at least mostly to play this game? (There are other PS3 games that I want to play reasonably well, too, but not as bad as this.) 
 
I just wish it was coming out on the PC or 360, my platforms of choice (in that order).

Lotsa reasons to have a PS3. You may see it as 95% for Heavy Rain now, but I'd bet that in time you'll find more things to justify owning one.  
 
May I suggest, Paul Blart: Mall Cop on Blu-ray? Perhaps Fat Princess would tickle your fancy.

Seeing as I bought a PS3 just for MGS4, I'd be stupid to criticise someone else for buying a console for one game.

I know that Uncharted 1 & 2 are action adventure games, but if you are really into story and characters these games are also a huge incentive to push you closer to a PS3

Demon's Souls!

" Demon's Souls! "

Heavy Rain does look awesome, but I don't think it's a reason to buy a PS3 just for that game.

Wait, it's a PS3 exclusive? Aw, bummer. Well, I'm not too interested in it, to be honest, but like others said, there's plenty of great exclusives on the PS3 now to make it worth having.

The PS3 is worth getting just for the exclusives. Get one!

That's not actually that bad. I bought a PS3 just for Tekken: Dark Resurrection.

I applaud you.  If I had 300 dollars, then I would do the same.

I think you should go for it. It's not like Heavy Rain is the only game worth buying on PS3 right now. Buy it for Heavy Rain. Enjoy it for more than Heavy Rain.

Well, I got my PS3 just for LBP and Heavy Rain. Didn't regret it for a second, atleast regarding the LBP part since Heavy Rain isn't released yet.

It's no longer cool to be hating on Ps3.  Pick one up and enjoy the games already.  You should check out all the exclusives all the way back to Heavenly Sword.

i bought my ps3 for virtua fighter 5, with ninja gaiden sigma on the horizon
 
not only are there like 40 more good games for you to play now, but it's $300 cheaper.
 
perspective.

I wouldn't buy a PS3 just for this game, but there are enough good games for it that you should probably consider it.

Buying a console mostly for one game is kinda dumb.

Huh? It's only bad if u can't afford it. Otherwise you'll end up getting more PS3 exclusives anyway. Win/win!

Heavy Rain, Uncharted 2, MGS4, MAG....... What more do you need?

Its more the straw that broke the camel's back for me.

I played the demo, it's utterly absorbing, but there's a long way to go yet. I'll wait for the crew's verdict before deciding on a day one purchase.
 
The PS3 is a pretty sweet machine. I also own a 360, and I love that too. I'm really looking forward to getting around to Mass Effect 2.
 
If you can afford both consoles, then get them. They're both excellent machines. "Get off the fence!" you say, but it's true. 
 
There are some fantastic exclusives on both systems, all of them well known to anyone reading this thread. Scientific fact.

There are so many amazing games on ps3 though dude. 

Not at all. If you have fun, then it doesn't matter.

It's not a good idea to buy a console for one game, especially a game that like Heavy Rain that will most likely be pretty short.

Not that bad, they're cheap(er) now!

I certainly wouldn't buy it to play Heavy Rain.
Then again, I wouldn't buy Heavy Rain to play Heavy Rain.
 
Still, I have one and would buy one to play a number of other exclusives.

I don't think any game is worth a $360 console/game purchase but I think that PS3 is certainly at a point that there is enough unique things between PS3 and PSN games (not to mention, a great bluray and dvd player) that it is absolutely a console worth owning. While no game is worth $360 dollars, I certainly think Heavy Rain is enough of a catalyst to push toward making the purchase.

Well it's fine to buy a console for a game, I bought my xbox for Halo 2, and my PS3 for MGS4. Hell I bought a wii for mario galaxy, and ended up staying for No More Heroes. It's fine. You usually end up finding other games you're into, and liking some of the unique aspects of the system. I've really given my PS3 more use since, since I mainly wanted a blu-ray player and MGS, but now I've been playing Uncharted 2, and inFamous and other things. So you never know. I say most consoles out are worth owning. I mean I was a bit disappointed with my Wii after enjoying 5 or so games, and I don't really play it anymore, but everything else I've bought for one game I've stuck with. 

Go for it. I got mine for MGS4 and kept it because of games like LBP, Demon's Souls, Uncharted 2, and now Heavy Rain. There's also the weird occasional PSN exclusive (The much debated Flower, Trash Panic, etc.)

So I walked into Walmart last night for a short shift, fully prepared to purchase a PS3 and Heavy Rain and maybe another game on the way out. 
 
But... I guess our local Walmart is all out of PS3s. So they checked online... oops, they're all out there, too. Apparently they've been out for awhile, and they have no knowledge of getting any more in the near future.
 
So now I'm going to go PS3 hunting at some point, checking out local stores to see if anyone has one. I won't get my discount (10% at Walmart), but meh. It just kind of sucks, though, because I thought all this supply-and-demand bullshit over PS3s ended like two years ago.

No, because eventually you'll start getting the other great games coming to the console, also god of war 3 is a little over two weeks away, and if heavy rain isn't a reason to buy a console that game is.

Dude, was totally thinking the same thing!! But I have to buy a car atm so can't and probably won't, but really want to play it and Uncharted 2

It ain't bad, I'm getting a phat PS3 ordered just for MGS4, and hopefully Demon's Souls. What really motivates me to get consoles nowadays are the exclusives.

It is worth buying a PS3 for this and MGS4. Seriously.

I bought my PS3 specifically for this game.  It's not that dumb, because now I have a Blu-Ray Player.

I don't think that's that awful of an idea. If you buy a PS3 and Heavy Rain it's very likely you will start getting games for it. There's are plenty of past and current exclusives to justify the price of one.

Buy a PS3 for this game, stay for God Of War III.
