In a word: wow. It’s rare that we ever see sales figures from Valve’s Steam digital distribution service, but in a recent blog post, Garry’s Mod creator Garry Newman decided to divulge those all-important figures. According to Newman, sales of the title have amassed 312,541 units since the modification’s introduction two years ago. With each copy priced at $9.99, that amounts to a hefty $3 million in revenue. Funny thing is, he wasn’t expecting the mod to be as popular as it is now.

The popularity took me and Valve by surprise. As soon as it went on sale the steam servers were temporary knocked out, due to the demand. On the first day it sold 5,729 copies. Wowzer.

I kind of expected that it would sell a big number of copies for the first day, then sell very few after that. I was kind of wrong, because over the next 2 years it went on to sell 312,541 copies. Which has totally knocked my socks off.

Not bad, not bad at all. Congrats Garry.
