What measures are Sonic Team taking against cheating and hacking?
On the PC version of the game, Sonic Team are using nProtect GameGuard in order to monitor computers for applications that can be used to modify the game or otherwise cheat in-game. This is the same program that was used on Phantasy Star Online: Blue Burst, and most programs used to cheat on that game do not work currently. It can be suspected as well that Sonic Team have implemented their own internal measures against cheating as well. This may be a major difference from all versions of PSO, which did not appear to give much consideration to security (hence the rampant cheating on several versions). GameGuard will not be used on PS2 and Xbox360, for what should be obvious reasons (you can’t run other programs on them). Also, it will be worth pointing out that PSU utilizes server-side saving for Network Mode characters. Story Mode and Extra Mode are client-side, however.
