...until 19th October 2009 you can buy World of Goo for any price you want, except zero dollars.  EDIT: Extended to 25th October!

World of Goo is 1 year old today! How time flies… the 2DBOYs are so proud!

To celebrate the occasion, we thought we’d try a fun experiment – starting today and ending on October 19, you can buy World of Goo at whatever price you like – one cent, a million dollars, the usual twenty, or any creative number they let you type into the text field.  If you played and liked the game but hadn’t yet paid for it, this is your chance at redemption! 

I didn't like the demo so I won't be downloading it. It'll be interesting to see what the majority of people pay for it. There will obviously be loads of people who won't pay.
I think it was on the Rum Doings that they were talking about when Radiohead did this, so this will be cool to see.

"There will obviously be loads of people who won't pay."

This is awesome! I bought the wii version on day one, it will be nice to have it on my laptop too.  I'm thinking I'll pay... 5 dollars...maybe? Ack, paying one cent is so tempting.

So many assholes are gonna buy this for one cent.

That's effin' weird, has that ever happened with a game besides this one?

I'd buy it for $.01, but it's Paypal and my Paypal is empty. Eh... the game isn't even worth that much, really. I thought it was pretty ass.

World of Goo was my GOTY 2008. If I was a paypal user I think I'd donate a little cash to 2DBoy.
 
And another good attempt at making people pay for software other than pitiful "anti-piracy" measures.

Kotaku just posted this and now the server is dying on its arse.

Totally got it for one dollar.

You do not have to have a Paypal account to buy it, you can just use a creditcard.

Stop being stingy pricks. You're happy to spend $60 on the next generic FPS but not $5 or $10 on a fantastic indie game?

This should not have to happen, but if it gets the game out to more people then good for them.

I already bought it for the Wii. 

That's fairly lax of them to do this. It's worth the 20 though, if you're willing to pay for it anyway.

I bought it for 5 bucks on a Steam sale...
 
Totally worth it.

" World of Goo was fantastic.  I really hope some people pay for this.  2DBOY should get paid for making such an enjoyable game. "

im going to buy it for 1 penny just because people are saying not to.
 
im that bad.

" I bought it for 5 bucks on a Steam sale...  Totally worth it. "

I bought it for $70

Goddamn, server is so slow right now.
 
 
Can't wait to buy this for one cent.

I'd buy it for thirteen dollars and thirty seven cents.  
13.37 
or eighty dollars and eight cents 
80.08 
 
lol, 8008s

I think 10 or 15 is a reasonable price 

Let's get a bunch of people to buy it for 8.8.

" That's effin' weird, has that ever happened with a game besides this one? "

" Let's get a bunch of people to buy it for 8.8. "

I'll pass.  I've already got both the Wii and PC versions. 
 
With that said, there's no excuse for anybody to not buy this game.

Anyone's who's interested, Kotaku posted the results of the experiment.  nearly 17,000 people paid a whopping $0.01 to paypal for the game (since Paypal took all the money which didn't even cover the fees). 
 
My wife picked this up on Big Fish two months ago for $6.99, so no need to buy again.

Here's the Kotaku article. 
 
I'm surprised that 4 people bought it for $50.  Must have money to burn. 
 
I would think that $5 would be the ideal price to buy it at nowadays.

This was an interesting "In Rainbows" experiment. I already bought it for $5 on Steam but any price is a good price. :)

This is pretty neat. I actually bought it for $15 on Virtual Console for the Wii. While I do think it's a good game, I thought $15 was a little steep. Still, I hope this goes well for them and that people don't all pay the minimum 1 cent for it.

I picked it up and I had this weird internal battle where my cheapness and my love of games fought over what price I should get it for. The love won and I paid $15 for it, definitly worth the price and I dont need to feel dirty for only paying 1 cent. Also props to them for making a Linux version of the game, its the only game I have on my computer so its gonna get a lot of playtime in the near future

Offer extended to the 25th of October for all those still interested.
