I would be interested in such a game that appropriately reckoned the costs and hazards of space transport, because the availability of unclaimed resources makes the expense and danger of stealing resources developed by others utterly insuperable IRL. I believe this would enable people to grasp the true win/win nature of development of offworld resources, perhaps sparking greater investment in what will be the greatest economic advance in history when we begin acquiring the almost illimitable resources available off world.
Asteroid Psyche, a remnant of the destroyed planetary core that comprises the bulk of the asteroid belt, has been estimated to be worth between ~$1Quadrillion and ~$10Quadrillion, which is greater than all the economic value of all development undertaken on Earth in history.
Thanks!
