The first game crowdfunded on Fig has generated a tidy return for backers in just two weeks on the market.

Kingdoms and Castles by Lion Shield has already earned a 100 percent return for its backers, and it's possible they will continue to see returns from the game for the next three years.

The medieval city builder generated US$1m in sales during its first two weeks, and earned enough money in 48 hours to cover initial investments, which took place back in January.

Fig is a crowdfunding platform for video games that allows backers to invest in a game to obtain shares in its future revenues.

Since its launch in fall of 2015, it has hosted three of the top four video game crowdfunding campaigns, and some notable projects on the platform include inXile's Wasteland 3, Obsidian's Pillars of Eternity II: Deadfire, and Double Fine's Psychonauts 2.

Fig was launched in August 2015 by former Double Fine COO Justin Bailey.

"Fig takes the best instincts of the community and combines them with a publishing model that gives control back to the developers and the fans that believe in their projects – today we proved that community publishing is a successful way to launch a video game," said Bailey.

"By sharing the commercial success of a specific project with supporters, community publishing shifts the focus from that of just successfully funding games to instead focus on the successful development and commercial viability of the titles. "
