Nice job there with Octopus (and of course all the other artwork as well)
Haze, really appreciate the videos!
The Octopus overlay seems to have been done using another process than the inlays for the later games. I also noticed this when scanning the inlay and carefully tried to separate the layers but without success. I think it was printed several times on the same surface. The material is also a bit different and the frame is brown instead of black.
The display dots seems to exists on all games but they are more or less visible on different games. Fire is the most extreme that I've seen so far. Perhaps the displays get worse with age and depending on how the display (or actually the polarizer and overlay) has been handled and stored is affecting the dot effect?
