10. Saints Row 2
Saints Row: The Third is one of my favorite sandbox games, but it is built on the foundation constructed by Saints Row 2. The first game in the series, while fun, was basically another GTA game with fewer features and better graphics. It was with the sequel that developer Volition really attempted to strike out and craft a bombastic, irreverent open world romp. This is a series that went from sniping rival gangbangers from a construction site in one game, to causing property damage by spraying everything in sight with a septic truck. The entire series received a new mentality, one of outlandish silliness and extreme profanity, all with a keen awareness of its own vulgarity. This mentality is further refined in Saints Row: The Third, which featured a grenade-type weapon called the Fart in a Jar.
