Syncing a game over a client server connection is not an easy task. It’s actually extraordinarily difficult and is almost completely reliant on the quality of interpolation. Due to the nature of interpolation, it gets exponentially more inaccurate the more time is spent doing it. Therefore, a game designer should want to minimize the amount needed. This is not an easy task, but it usually involves using the server as a middleman to halve the interpolation time.
