- There are several differences between the show version and the set version:
- In the sets, the cabinet is a bit larger, so a normally large minifigure can't stand in front of the buttons.
- In the sets, the inscription Prime Empire is below the screen while in the show it is above it.
- At the top of the cabinet has Unagami's insignia in the show, while in the sets it is missing.
- While the front of the cabinet opens in the show, the rear of the cabinet opens in the sets.
- Storage space for minifigure and transparent screen in the show is missing.
- The side protrusions on the cabinet are slightly larger in the show and are all yellow.
