Serious question for you gamers out there: Why would a person go to such great lengths to cheat at a video game? Is there a monetary incentive? Otherwise, it seems like a lot of effort just to increase one's standing on a leader board.

There's a monetary incentive as well. If you can reliably produce new cheats that aren't detectable, people will buy them. There's usually an incentive not to share private cheats because once it's public, it will still probably work but will definitely get you banned. Amateurs and professionals both pay for private cheats so besides the technical challenge, there is some money to be made.
