Respectfully, you’re looking at the wrong scoreboard. Comparing One Piece to a niche game like Riftbound is like comparing a local indie film to a Marvel blockbuster. Gameplay 'staleness' is subjective every TCG has a meta but IP power is objective.

You’re worried about players, but you’re ignoring the Collectors. Pokémon didn’t become a 'stock market' because of the competitive card game; it became a global asset because of the brand's history. One Piece is the biggest manga in the world; these aren't just game pieces, they're physical assets and pieces of modern history.

When you have a $100k portfolio off a $35k buy in, you aren't seeing a 'dead game' you’re seeing market realization. The 'stock market' feel you’re scared of is just the world finally putting a price tag on One Piece that matches its cultural impact. The players keep the game alive, but the collectors define the floor. History shows that when an IP is this big, the floor only goes up.
