Glitch is sunsetting, you're out of luck. If you're looking for many, many reasons why Glitch failed, then all you have to do is pull up a chair in front of Tiny Speck's Stewart Butterfield and listen to him talk. Butterfield spoke with Gamasutra about the myriad of reasons why Glitch didn't take and ultimately had to be shuttered.
"Ultimately if I have to identify one thing as the problem -- I don't think there is just one -- but if I had to choose just one," Butterfield said, "I think the game was too foreign of a concept for most people."
He pointed out that while there was a devoted fan base who "got it," marketing the title presented severe problems throughout most of the game's lifespan: "There haven't ever been other non-combat MMOs that are based on absurdity, humor, and whimsy. I'm not sure anyone has the specific expertise in making this thing work."
Other failures that Butterfield identified was a lack of fun gameplay until recently, the decision to do the game in Flash instead of for mobile platforms, large expenditures of money, and Tiny Speck's big team drawing salaries.
