CastAR’s collapse shows the incredible challenge of making AR games

CastAR was one of the most ambitious augmented reality game companies in the business. But it looks like it has shut down amid one of the most obvious problems in the fledgling industry: It was too early, and the challenges it faced were incredible.

CastAR failed to raise a new round of funding and shut down this week, according to a report from game news site Polygon. That spelled the end to a years-long project by former Valve employees Jeri Ellsworth and Rick Johnson to create a unique AR tabletop gaming platform, one that wanted to deliver the next step in a magical kind of play.
