It’s simple really, a game is released, many buy it but have never played it prior. Then decide it was fun and all, but ready to buy the next title. Does not mean it’s bad, it just means it’s not a permanent keeper. There is always the “shuffle” of games after initial release. Then the eventually find homes in places people love and play them. Then they are no longer for sale, or hard to find.
Example
Black Knight LE
Ghostbusters LE
Stranger Things LE
All fairly recent, no longer made titles, that are now much harder to find. I suspect Zeppelin is no different, once the shuffle ends, people will be trying to find one.
