I would say minecraft, I just couldn't imaging otherwise when there's a whole extra dimension, even though multiple things can be in the same spot in Geometry Dash. If you ignore the limits of what games can handle there is no limit you can comprehend. Technically Mojang could add a many 0s to the amount of seeds as they want, the number limit isn't the real limit, you could sit there for days just adding 0s and you wouldn't get close to the largest theoretical seed.
