The cost (not simply in terms of materials used, but time and labor, and rejects) for making piecemeal HuCard cases might be higher than simply buying big lots of crappy games and harvesting the cases.
I agree. Unless there is a more efficient process that this guy can come up with, I am thinking that these cases will likely just be a really cool self project, and not really something that is able to be mass produced.
However, it would be pretty fun to see some colored cases. Arkhan needs to watch the YouTube video to see how to make Atlantean blue.
