Zeboyd Games announced that its Cthulhu Saves the World and Breath of Death VII Combo pack, which were priced at $3, has sold more than 100,000 copies on Steam between its launch on July 13 and the digital distribution platform's Halloween sale last month.

That's far more units than the studio sold with the original Xbox Live Indie Games releases -- Breath of Death VII has moved 55,000 copies at $1 since April 2010, while Cthulhu Saves the World went through over 20,000 copies at $3 since December 2010.

When Zeboyd initially launched the bundled two-pack on Steam and hit the top sales spot on the service earlier this year, it revealed the games "made more revenue in less than a week on Steam than [they] have in over a year and a half on Xbox Live Indie Games."

"The days of worrying over whether or not we could support our families while making games we would want to play ourselves are behind us," says the indie studio. "Counter-intuitive though it may be, there is obviously a definite audience for quality console-style RPGs that are aggressively priced on the PC."

Zeboyd is currently working on the third release of episodic series Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness (Hothead shipped the first two entries in 2008) for 2012, and has "many new intriguing ideas" for RPGs and other game types planned afterward.
