Responding to fan questions on Reddit, Monaco: What's Yours is Mine developer Andy Schatz claims that his studio's efforts in porting its co-op stealth game to the Xbox 360 were "largely wasted," due to unexpectedly low sales.

Schatz theorizes that many factors contributed to Monaco's poor sales performance on Xbox Live Arcade, including a weak demo and a last-minute delay that prevented a simultaneous release on PC platforms. Schatz revealed that a widespread bug related to online play proved especially troublesome, due to his team's inability to reproduce the issue on developer hardware.

"I was never depending on the Xbox being our primary revenue generator, but I was very disappointed in Xbox sales nonetheless," Schatz said. "We put a ton of effort porting the game, and to have that effort be largely wasted was really disappointing."

The PC version of Monaco is currently taking part in Steam's Summer Sale, and will be featured in an upcoming community vote.
