Then purchase the game legitimately through Steam – it will run natively or via Proton. Do not download or run any file claiming to be "Civilization VII" from unofficial sources. Wait for an official announcement from Firaxis/2K. For now, enjoy Civ VI or older titles on Linux through official channels.
