DEFCON 19: Hacking MMORPGs for Fun and Mostly Profit
This is a real cool video although they talk about games like world of warcraft some of the concepts are the same. Such as when he talks about simulating a game client using packets instead of actually playing the game so he can run 100 games on a single pc. Also the part where he talks about how to find exploits is very true of neopets. Worth a watch at least.
