Off topic question. Has there ever been widespread hacking in an online console game? If not, then I think my choice here may be clear. The number one most annoying thing about pc gaming is hacking. (Although I'm going to want the hack that makes people think I'm using a six-axis when I'm really using a mouse.)

 No, there hasn't, but games like UT -- and any game with significant flight time and trajectories -- has never been prime hacking territory. Games such as CS with instantaneous flight pathing are the ones that are really in trouble. 

 For those who missed it, bod is talking about bullet/projectile flight times.  Basically its easier to hack when the bullets are automatically where you are pointing versus when the bullets actually have to travel.  Because when the bullets are tracked by the engine the opponent can try to dodge etc and you have to take that into account for an aimbot etc....

Yeah, thanks Sqrl!

Simple example: RPGs that fire and have a missile travel across the screen. Every time the game processes, it has to recalculate the position and trajectory of the missile on the screen. That's, oh, hundreds of times a second, at least. Hacking that is hard.

In Counter Strike, as the classic example, most bullets leave the gun, and are instanteously placed wherever they were fired. So if I were shooting at a person, and I click the trigger, the bullet goes from inside my gun to inside the person instanteously. There are no flight time or trajectory calculations for the bullet. That's much easier to hack.

Unreal Tournament has many guns that have bullets (or rockets) with flight times / trajectories. Not all, but many. This makes the game automatically much more difficult to hack.

Good point.  But you're referring to only one particular hack (aimbotting).  There are plenty of others, but as long as they keep people from installing their own dll's, none of them should be a problem.
