The approach Postindustrial Games have taken with the Major Zack free figure is interesting, I have not seen that in a KS campaign before. You only get it if you held a qualifying pledge for the specified 48 hours during the campaign, and those 48 hours expire before the "remind me" notices are sent out by KS.
Rewarding the backers who have been with the project during the campaign, rather than waiting for the last minute joiners.
Noy only is this a great looking game, but there is a lot to like in the way it is being run.
