I’m surprised we never covered this before. The game World of Goo is a very popular PC/Wii puzzle game created by independent developer 2d Boy. The game was released in October of 2008, and as a celebration for the game’s 1-year birthday, they decided to offer the game for whatever YOU decide to pay for it! The developers, after offering the sale for about a week, did a very interesting analysis of what price people paid. The average price of the game was $2.09, and the vast majority of people paid a single cent, but they have data going up to $50.99, which is interesting. I imagine that’s people who have already bought and loved the game.

I just bought my copy, as passing up a practically free game is against my morals. (I won’t divulge how much I paid, but it wasn’t the $19.99 price on Steam!) This game is supposed to be fantastic and really, if you want, you can pay a single cent for it. You may as well do it.

Head here to purchase the game. Unfortunately, you can’t buy directly through Steam with the pay-your-own-price option.
