You need ALL of the books.
I used to hack games, and after i made an aimbot and shooting through walls and fly hack and all the features you see these days, it got really boring cuz there wasn't anymore of a challenge. I found myself to start shifting toward real software programming and making software which helped people instead of undoing people's work (game hacking). Lol, i think a game hacking site was the best place for me to this, hehe.
