Garry Newman, creator of the brilliant sandbox Source mod, Garry's Mod, has posted a graph of the game's entire Steam sales history on Twitter. The graph features a red line that represents Garry's predicted sales, and a white line that depicts the actual sales. There is quite a big difference. Garry predicted that interest would tail off towards the end of 2009, but it just kept on going, and going. It's selling more than twice the number of copies each week than it was when it was first released back in 2007. Take a look.



Look at those spikes. The mini jaggies are all weekends, the massive spikes will be Steam sales and promotions. Garry confirmed to a Twitter inquirer that the graph shows the sale of 1.4 million copies. The steady growth of Garry's Mod will be down to more than just word of mouth. Garry's Mod receives constant updates, all of which are listed over on the official Garry's Mod site. In short, Garry is probably doing quite well from his creation. The success of Garry's mod shows that supporting a game for a long time after release can pay off quite spectacularly.

Garry's Mod is available now on Steam. The outdated Garry's Mod version 9 is free. It doesn't have all the features of number 10, but serves well as a demo if you want to check it out.

Back in 2004, Garry's Mod turned Valve's Source Engine into a toybox. Its intuitive UI, straightforward controls and building tools removed the programming barriers needed to be creative with Source. Since then, hundreds of thousands of people have used the mod to attach rockets to the G-Man's head, build a giant robots or mess around with the physics system. The community has created hundreds of new game modes, mods and machinima using the tools.

Today, developer Garry Newman posts on his his site to announce that Garry's Mod has now sold more than a million copies since its launch on Steam in 2007.

"This is a pretty big deal for me considering this all started off as a tiny tiny modification about 6 years ago," writes Garry. "This is more than I could have ever expected or wished for!"

"Even though my name is on the Mod there are a lot of people that have helped out over the years – and GMod wouldn’t be where it is now without them. Particularly Valve & Steam – which made Garry’s Mod technically feasible"

Garry's Mod is available to buy on Steam now for £6 / $10. Garry's Mod 9, an older version with less features, can be downloaded from Steam for free.

The great thing about Garry's Mod is that it simply gives you an arena and gives you all the tools needed to build anything you want. Many Garry's Mod players have found that the best part of building something is the bit at the end when you use a nuclear bomb to blast it to smithereens.
