I think they've done a pretty good job. One more patch for C2 would be great, but I doubt that it will happen.
It's a pity that developers have to waste time, energy, and computing power on trying to make a game secure. Imagine how much better the games would be if they didn't have to do that. They would all have better graphics and run more smoothly.
I certainly don't blame HVS for the hacks. It's like saying it's my fault if my car gets stolen because I didn't lock the door.
I will keep an eye on whatever HVS does in the future, especially in the FPS genre.
