At that level of desired control it seems like they would be better suited to writing a script or novel. My its very nature a MU will have multiple folks each with a slightly different idea of what the setting and genre are. Ideally you have a staff that is firm enough to provide coherency while also giving players enough freedom to stretch creatively. that place sounds limited to the extent that you would be expected to follow a script without the courtesy of being given one.
