BD 154 Queen of Earth

[ChunkyLover]

Weird, seems to be OOP without many (any?) options from third-party sellers on a cursory internet search

That's pretty much the norm with most OOP Eureka titles (it was a real waiting game for me to find a decent price or eBay listing on "Rapture"). I think this title went OOP a long time before Eureka's de-listing on their site as it was "Out of Stock" from direct since at least early 2020.
