In addition, customers really don't care how you got the funding. They want the product and are not particularly interested in how you made it, ergo, it doesn't matter to them if funding for it came from Kickstarter or from a family loan. The only benefit putting the logo on the package might come if customers view Kickstarter as a reliable vetting service, indicating that products funded through Kickstarter have undergone some scrutiny, similar to "As Seen on TV" blurbs seen on many packages. Buyers believe that, in order to get on TV, a product must undergo some sort of examination, so the "TV" blurb lends some credibility to the product.
Games would probably do better to pursue an "As seen on TableTop" logo, as that lends some creditably to the product, at least within the gaming industry, since many of their customers have some familiarity with TableTop.
