Ezio Melega It can be easily replaced by a slotted die cut disk or even a square card. But making it a system of rotating die cast gears is an expensive gimmick that has zero to do with the setting. I’m not saying it does not do anything, or that the game mechanics that rely on it are not fun, but that it’s just a gimmick. Could have done the exact same mechanics other cheaper means. I’m tired of explaining again and again, so I just leave it as an exercise for the reader.
