Do you have XNA and .Net?
No, Infiniminer is better in sandbox, you just dont know how to dot he fun stuff.
it requires a shader what the hell? help

Actually, I think the greatest mining game ever would be a 3D multiplayer version of "MotherLoad".
Have you even played brominer? you can spawn lava and water and rainbow road bricks it's way better for sandbox.
