It is possible, but certainly very hard to get off the ground without robux.

Your source of revenue would be gamepasses, but you can also get robux via working in other Roblox groups who give out robux. Do not use third-party websites to get robux.

With the robux, you can sponsor/advertise your game to get more players.
