Oh wow, it started as a game concept! I was just thinking I wish they made a videogame with the physics and geopolitics (stellar politics?) from the show.
There is an Expanse board game[0] that might interest you (it's been described as being like the cold-war themed classic, Twilight Struggle, but for up to 4 (TS only plays 2):
The Expanse, a board game based on the Syfy television series of the same name, focuses on politics, conquest and intrigue similar to the board game Twilight Struggle, although with a shorter playing time. The card-driven game uses key images from the show, along with action points and events that allow players to move and place "Fleets" and "Influence".
In more detail, players represent Earth's UN forces, the military of Mars, the rebels of the O.P.A., and the mysterious corporation Protogen Inc. Each player has special abilities that must be maneuvered to gain advantage. Players increase their control over the solar system using characters and events from the universe of The Expanse.
(There's also expansion, The Expanse: Doors and Corners, that adds new tech, leaders, the protomolecule, etc.)
The only problem would be finding a reasonably-priced copy as it appears to be out-of-print, which can lead to the price of second-hand copies going way up.
I kid but not really. The Expanse might be fictional but the threat it raises and considered with here isn’t - it’s good to see this as a proof of concept but there lots more to be done, detection included.
