The game will be free-to-play and the devs promise that it will be possible to complete the game from start to finish without spending any money. However, there’s in-game currency that can be acquired with real money to show “an expression of gratitude for our efforts and work”, and required to “maintain the atmosphere of a game”. What that means exactly I couldn’t find out.
Dodo Games promises an “immersive, beautiful space adventure in a hard sci-fi genre”. An interesting aspect of this space game is the use of real astronomical data, so the stars of our own galaxy are accurately represented. One of the purposes of this game, say the devs, is to be used as an educational tool also, where children can get acquainted with our galaxy and get to know the location of our own star and the names of the other stars near us, planets, etc.
