There's no information about how this loose chip got inside the case in the first place, but it's safe to say it shouldn't be in there. It's also unknown if it actually works or what it could potentially contain if anyone was able to get it up and running. Maybe it's the first half of the game.
We're also left wondering what has happened to the top section of the card. What if there's another Switch owner out there who opened up their new copy of Civilization VI and found this other half? We can only hope the factory that packaged this game sees this news doing the rounds and tightens up its production line so it doesn't happen again.
Have you ever found anything weird in one of your game cases? What do you think is on this chip? Tell us down in the comments.
