There are a ton of great games on Xbox Live, but it seems Steam is a much better platform for indie game developers to earn a decent amount of cash.

Robert Boyd‘s Breath of Death VII and Cthulhu Saves the World was recently released on Steam, and made more money during a week on Steam than the 18 months the games spent on Xbox Live.

Zeboyd Games, Boyd’s company, announced this on their company blog recently, stating the steam sale was a “tremendous success”.

“We are pleased to announce that Zeboyd Games has already made more revenue in less than a week on Steam than we have in over a year and a half on the XBox Live Indie Games service.

Thank you again to everyone who has made this huge success possible!”

Breath of Death VII and Cthulhu Saves the World was released on XBL Indie Games in April and December 2009, respectively. BoDVII has sold 50,000 copies for $1 each, and CStW has sold somewhere between 16,000 and 17,000 units or $3 each sine launch.

The Steam bundle, which sold both games for $3, mae $100,000 in a mere six days. Whoever said PC gaming doesn’t pay off doesn’t know what they’re talking about!
