Get updates from the project as they are made throughout the campaign and product development.
Also, gain access to additional IGS products, both published and planned, as Add-Ons via BackerKit once the Kickstarter campaign wraps up.
And get your name in the "thank you" section of the final product.
Not terribly exciting, right? You should probably scroll down and pledge at a higher, more interesting, level.
Some pledge levels involve multiple products, and some involve dozens of products that are part of a planned product "pipeline". In all cases, the "Estimated Delivery" of a pledge level reflects when delivery is scheduled to *begin*, not complete.
All other pledge levels receive these minimum acknowledgments and benefits.
