One that isn't often mentioned, and it seems odd to me that this would be rare, but a *complete* copy of the Switch version of the Skylanders: Imaginators Starter Pack appears to be quite hard to find.

The Switch version released five months after the other platforms at the Switch hardware launch in March 2017. By that point it was clear that the game was a massive sales disappointment.

It's my understanding that the game sold approximately 200K across all platforms in the US, with the Switch version representing a small fraction of that. Likely somewhere in the low 5 figures. Who knows how many of those are still complete in box?
