In its 10 years since debuting as an original Half Life 2 source mod, Garry Newman's open-source sandbox title aptly named Garry's Mod has now surpassed 3.5 million sales to date.
Speaking with Rock Paper Shotgun
, Newman revealed a number of reason as to why Garry's Mod has gone so wild, naming Steam as the number one cause of its success. Other reasons include user-generate content playing a key role, additions from other Valve games like Team Fortress 2 which in turn keep the game fresh and the modern prevalence of video game footage on YouTube to capture the wacky and crazy creations.
Interestingly, Newman revealed that Minecraft - a similar open world title allowing players to build only to their imagination's limit - wasn't actually such a detriment, instead aiding Garry's Mod to become even more popular. "You’d think Minecraft would kill GMod’s popularity… but it’s kind of the opposite," Newman stated.
"People play Minecraft to death – they love it.. so they go out looking for other games that are a bit like it. Minecraft has attracted a lot of people that aren’t really PC gamers too. They play the game on the 360 or the iPad and everyone tells them that the PC version is better."
