I&#x27;m still constantly shocked at how many games do this.  In the MMOG world it is really easy to do everything right, UO came out in 1997 and the devs outright told everyone working on similar games &quot;never trust the client&quot; and &quot;the client is in the hands of the enemy&quot;.  Yet games like FFXI and WOW that came out many years later have the client setting the position of the player and the server just blindly accepting it, allowing for common and popular speed&#x2F;pos hacks.
