Play to Earn Game -- 2

Hello , i am interested in a crypto / blockchain play to earn metaverse style game , it would be a game to populate mars and build cities , buy and sell land and collect materials from terrain to buy more land and build more citys , its kinda something like starcraft but on mars and play to earn / blockchain , is there also a option for a demo build and later to finish the product and what are the costs ? Thanks
