Today I posted a video pretty much summing the entirety of my research on this combo pack.
About 12 hours later, I get a message on my channel’s Facebook page with the following images. They are from a sealed copy of the game.
If you notice, it’s not even the box art that appears on Amazon and Lukie Games, but rather the “variant” I had included earlier in this thread (see DeeDee’s foot).
This has been a really enjoyable journey and I appreciate everyone’s assistance getting to this point!
Does having only one UPC number mean the games are on one cartridge?
