GDC talk Depth in Simplicity: The Making of Jetpack Joyride, Halfbrick Studios' chief creative officer Luke Muscat shared the story of the 11th hour name change for Jetpack Joyride, which was originally supposed to be called Machine Gun Jetpack.
"I'll tell you, we almost changed the app to this name because we thought by making it too drastically different we were going to undermine all of our marketing effort, but we actually had this name for a while: Machine Fun Jetpack," Muscat said. "At the time, we were like 'that sounds alright, maybe I could live with that.' Then I got in the next morning, and I walked up to Phil's desk, and we both said the same thing at the same time: 'What the fuck were we thinking?' I'm so glad we didn't go out with that name."
