MICADO is the multi-AO imaging camera for the E-ELT. It has been optimised for use with MCAO, but will have its own SCAO module for the initial operational phase at first light, and will also work with GLAO. In this contribution, we outline the science drivers for MICADO and show how these have shaped its design. The science drivers have led to a number of requirements on the AO system related to astrometry, photometry, and PSF uniformity. We discuss why these requirements have arisen and what might be done about them.
