I almost worry that the Petersen's don't really want to showcase too many painted editions of the game for fear of people not liking the stock game. It's an odd thing really. I would hazard to guess that a majority of people would rather have painted versions of the figures if they could afford them. There is so much detail in the sculpts that'd it be a sin not to paint em'.
Are the figures 'hand sculpted' or were they originally designed with a high-end 3d printer then molded ?
