you could even create a perceivably "spherical" planet map inside a video game/simulation as a 3d model. all it has to do is be big enough that it translates into looking mostly flat in first person view. high polygonal count obviously. i don't know why people are so quick to rule out the simulation theory, or even flat earth. flat can merely be a matter of perspective with varying scale. what is a plane after all? not saying i believe in these things but you can't really disprove them either.
